b53f595b3e Fix -nopie/-nopie check. 
We don't use lgcc_s but missing lgcc_s or another library cause test to fail.
So use -nostdlib.
We need to use -Werror to avoid warning-generated case to be accepted.
Clang uses -nopie rather than -no-pie. Check both and use whichever one works.
Additionally android clang passes -pie to the linker even though it doesn't
define __PIE__. So if compilation without no-pie logic fails add -nopie/-no-pie
even if __PIE__ is not defined.

a3e9da054d configure: add check for -no-pie if the compiler default to -fPIE 
When Grub is compile with gcc 6.1 that have --enable-defult-pie set.
It fail with.

Makefile:26993: recipe for target 'trig.module' failed

Check that compiler supports -no-pie and add it to linker flags.

0d7c7f751d use TARGET_LDFLAGS in grub_PROG_OBJCOPY_ABSOLUTE 
That's what Makefile will use and it is required if unusual flags
must be passed to linker (e.g. to build ppc32 code on ppc64le with clang).

6505b241fd Remove obsolete ADDR32 and DATA32 checks. 2015-02-21 17:44:41 +01:00

e0a850947f fix removal of {cpu,machine} links on mingw/msys 
At least on Windows 2003 using "ln -s dir1 dir2" in msys shell succeeds,
but results in what looks like hard link. Subsequent "rm -f dir2" (e.g.
during second config.status invocation) fails. Check that we also can
remove link to directory.

Make it more clear in message that we are checking "ln -s".

37378f748a Define functions explicitly rather than using --defsym in tests 
whenever possible. Respect locality in remaining cases.
