And what host GCC version are you using?
I just tried a build with HOSTCC=gcc-4.1 and it indeed fails for me
(but with another error):

gcc-4.1  -c  -W -Wall -Wwrite-strings -Wstrict-prototypes
-Wmissing-prototypes -Wold-style-definition -Wmissing-format-attribute
-Wno-overlength-strings -pedantic -Wno-long-long   -DHAVE_CONFIG_H
-I. -I/tmp/br/mips-4.1/toolchain_build_mips/gcc-4.3.2/fixincludes
-I../include
-I/tmp/br/mips-4.1/toolchain_build_mips/gcc-4.3.2/fixincludes/../include
/tmp/br/mips-4.1/toolchain_build_mips/gcc-4.3.2/fixincludes/fixincl.c
/tmp/br/mips-4.1/toolchain_build_mips/gcc-4.3.2/fixincludes/fixincl.x:7947: warning: string length `575' is greater than the length `509' ISO C89 compilers are required to support
cc1: error: unrecognized command line option "-Wno-overlength-strings"
make[2]: *** [fixincl.o] Error 1
make[2]: Leaving directory
`/home/peko/tmp/br/mips-4.1/toolchain_build_mips/gcc-4.3.2-initial/build-x86_64-pc-linux-gnu/fixincludes'

Which for a bit of testing seems to be caused by the combination of
-pedantic and -Wno-overlength-strings (any of the two are ok, but the
combination isn't).

That's with:

gcc-4.1 (GCC) 4.1.3 20080704 (prerelease) (Debian 4.1.2-24)
