I meant the build tree.
I can't find 'libgcc.a':
/tmp/nix-build-gcc-cross-sans-libc-mips64el-linux-gnu-4.7.2.drv-0/build/build-i686-pc-linux-gnu/fixincludes# file fixincl.o
fixincl.o: ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), not stripped

I don't think so.
config.log:
configure:2785: gcc -c -mabi=64 -g -O2 --host=mips64el-linux-gnu conftest.c >&5
gcc: error: unrecognized argument in option '-mabi=64'
gcc: note: valid arguments to '-mabi=' are: ms sysv
gcc: error: unrecognized command line option '--host=mips64el-linux-gnu'
[...]
ac_cv_env_CFLAGS_value='-mabi=64 -g -O2 --host=mips64el-linux-gnu'
Then I tried to use #:make-flags instead:
((#:configure-flags flags)
`(cons ,(string-append "--host=" target)
,flags))
;; MIPS64
((#:make-flags flags)
`(cons "CFLAGS=-mabi=64 -g -O2"
,flags))
((#:phases phases) ...)
And got the same collect2 error as before:
collect2: error: ld returned 1 exit status
make[2]: *** [/tmp/nix-build-glibc-cross-mips64el-linux-gnu-2.17.drv-8/build/libc.so] Error 1
make[2]: Leaving directory `/tmp/nix-build-glibc-cross-mips64el-linux-gnu-2.17.drv-8/glibc-2.17/elf'
make[1]: *** [elf/subdir_lib] Error 2
make[1]: Leaving directory `/tmp/nix-build-glibc-cross-mips64el-linux-gnu-2.17.drv-8/glibc-2.17'
make: *** [all] Error 2
I checked 'config.log' and found out that 'ac_cv_env_CFLAGS_value=' is
empty. Does it mean that #:make-flags are not honored?
I tried to add the above 'CFLAGS' to GCC's #:make-flags, but it also
failed.
I also tried the same with '-march=mips64'.
