Consider the following output:
------------------------------------------------
> ~/bin-trunk/bin/gcc --help=target
The following options are target specific:
-m128bit-long-double sizeof(long double) is 16
-m32 Generate 32bit i386 code
[...]
-muclibc Use uClibc instead of GNU libc
/usr/lib/crt1.o(.text+0x18): In function `_start':
../sysdeps/i386/elf/start.S:98: undefined reference to `main'
collect2: ld returned 1 exit status
------------------------------------------------
This happens with any --help= option.
It looks like the "--help=" option isn't turning off the parts of the compiler
that do compilation, and so it's still trying to link an empty program.

Summary: gcc --help=target gives a linker error.
