* configure.ac: Test if '--build-id=none' is supported by the

linker.  If yes, add it to TARGET_LDFLAGS.  Build ID causes
objcopy to generate incorrect binary files (binutils
2.17.50.0.18-1 as shipped by Fedora 8).
* aclocal.m4 (grub_PROG_OBJCOPY_ABSOLUTE): Use LDFLAGS when
linking, so that build ID doesn't break the test.
