Hi,
Setting $CC to another gcc (not in the path) fails when attempting to
configure for 64-bit EFI if the installed gcc cannot handle -mcmodel=large.
configure.in should be changed to honor $CC. I'm horrible at m4 / autoconf,
so I'm not sure what needs to be changed (otherwise, I'd provide a patch :)).
From config.log after running ( setenv CC gcc-4.3.2; ./configure --with-platform=efi --target=x86_64):
configure:6612: result: no
configure:6617: WARNING: -mcmodel=large not supported. You won't be able to use the memory over 4GiB. Upgrade your gcc
configure:6624: checking whether option -mno-red-zone works
configure:6652: gcc -c -Os -m64 -DMCMODEL_SMALL=1 -m64 -mno-red-zone conftest.c >&5
conftest.c:1: sorry, unimplemented: 64-bit mode not compiled in
--S
