ebe316e4df Discover which option provides soft-float on configure stage. 
Deals with clang needing other arguments to stop issuing floating
instructions than gcc.

f16b8c0405 Relax requirements on asm for non-BIOS i386 platforms. 
These platforms don't have a hard limit on size of resulting code16
code, so we don't care if assembly is bigger than necessarry.

065ad910f1 Test which flags make our asm compile. 
Previously we relied on assumption that clang always needs -no-integrated-as
but it's not always true.

2da4171eab configure.ac: don't use -msoft-float for arm64 
aarch64 toolchains do not support the -msoft-float option added by
commit 3661261f. Insted, for arm64 use -march=armv8-a+nofp+nosimd.

77063f4cb6 Fix in-tree --platform=none 
* configure.ac: Only remove include/grub/cpu and
include/grub/machine in the --platform=none case, not all of
include/grub.

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.

c2b70d0981 Explicitly check for linking format to use for efiemu64 module 
Similar to check for target linking format, also check for efiemu64
instead of hardcoding -melf_x86_64. This fixes compilation on *BSD
variants. We cannot easily reuse main target check because platforms
are different (main target is 32 bit and efiemu64 - 64 bit).

This commit adds EFIEMU64_LINK_FORMAT that contains detected
link option and is used in efiemu64.o linking instead of hardcoded
value.
