80fdaf1d01 configure.ac: Reorder efiemu check to after link format check.
efiemu is supposed to be disabled when compiling through exe format.
Unfortunately format was determined only after efiemu check. Reorder to fix the
problem

40051fedc3 configure: Add -fno-unwind-tables if supported.
Unwind tables are useless for us bt consume space if present. Ensure that they
are not.

5ae590b32d configure: Fix grub_cv_cc_fno_unwind_tables check.
Check tries -fno-dwarf2-cfi-asm but adds -fno-asynchronous-unwind-tables
to TARGET_CFLAGS. Fix this.

f1b3525385 Add -mno-stack-arg-probe on mingw.
This argument disables generation of calls to __chkstk_ms. Those calls are
useless on GRUB as function is dummy. Yet they increase module size and
use limited-range relocations which may not work under some memory layouts.
We currently don't use such layouts on concerned platforms but lt's correct
this.

a261842785 configure: fix macports flex version detection
Macports add extra information after version itself:

$flex --version
flex 2.5.35 Apple(flex-31)

We require at least felx 2.5.35 so do not need to care about prehistoric
"flex version n.n.n"; just use second field always.

be25d92196 configure: force o32 ABI on MIPS
GRUB code expects O32 or N32. N32 is less tested than O32, so we prefer to
compile with O32. Some systems (e.g. GNU Guix) default to using newer
n64 or n32 ABI. Try to find suitable options to force o32.

For GCC this is simply -mabi=32. While clang supports this option as well,
o32 ABI is valid for MIPS target and n32/64 ABI are valid for MIPS64 target
only, so use "-target mips/mipsel -mabi=32".

43d4231432 configure.ac: clean up arm64 soft-float handling
Fix compilation with gcc 5.1 (avoid internal compiler error), by
replacing explicit -march +nofp+nosimd options with -mgeneral-regs-only.

This also enables the removal of some further conditional build flag
setting.

064360e667 Remove libgcc dependency.
libgcc for boot environment isn't always present and compatible.
libgcc is often absent if endianness or bit-size at boot is different
from running OS.
libgcc may use optimised opcodes that aren't available on boot time.
So instead of relying on libgcc shipped with the compiler, supply
the functions in GRUB directly.
Tests are present to ensure that those replacement functions behave the
way compiler expects them to.

6a4ecd276e mips: Fix soft-float handling.

5d90f6e533 Add a new "none" platform that only builds utilities
This makes it possible to build generally-useful utilities such as
grub-mount even if the rest of GRUB has not been ported to the target
CPU.

* configure.ac: Add "none" platform.  Default to it for unsupported
CPUs rather than stopping with a fatal error.  Don't downgrade
x86_64-none to i386.  Define COND_real_platform Automake conditional
if the platform is anything other than "none".  Don't do any include
directory linking for "none".
* Makefile.am: Skip building grub-core and all bootcheck targets if
!COND_real_platform.
* include/grub/time.h: Don't include <grub/cpu/time.h> if GRUB_UTIL
is defined.

2a5a532c00 Support grub-emu on x32 (ILP32 but with x86-64 instruction set)
* configure.ac: Remove -m64 from checks for -mcmodel=large and
-mno-red-zone.  These are always either unnecessary (x86_64-emu) or
already in TARGET_CFLAGS at this point, and they produce incorrect
results when building for x32.
* grub-core/kern/x86_64/dl.c (grub_arch_dl_relocate_symbols): Cast
pointers to Elf64_Xword via grub_addr_t, in order to work on x32.
* include/grub/x86_64/types.h (GRUB_TARGET_SIZEOF_VOID_P,
GRUB_TARGET_SIZEOF_LONG): Define to 4 on x32.

dcecae1a49 reintroduce BUILD_LDFLAGS for the cross-compile case
This allows providing separate LDFLAGS for build and host environments, which
are not necessary the same for cross-compile case. In particular, it allows
building host programs statically to not depend on presence of libraries at
run-time (e.g. MinGW DLLs on Windows) while continue to use default dynamic
linking at build time.

Also fix obsolete comments in confgure.ac - we do use different environment
for build and host now.
