The issue with the spec file is caused by this in the Makefile.in:
# Dump a specs file to make -B./ read these specs over installed ones.
$(SPECS): xgcc$(exeext)
$(GCC_FOR_TARGET) -dumpspecs > tmp-specs
mv tmp-specs $(SPECS)
Debian's supplied gcc 4.3 is built androgynous:
# gcc -v
Using built-in specs.

Thread model: posix
gcc version 4.3.2 (Debian 4.3.2-1.1)
# gcc -dumpspecs | head -2
*asm:

%{m64:--64}
We need to check that the host-compiler's "spec" is correct and fix it.
Here is some pseudo-code:
if ' gcc -dumpspecs | grep \{m32:--32 | grep \{m64:--64 ' then # not correct
if test x`(hostname || uname -n) 2>/dev/null | sed 1q` == "xopensolaris" ;
then
if 'isainfo -k' = 'i386' then
gcc -dumpspecs | sed 2s/m32:--32/!m32:--32/1p
fi
if 'isainfo -k' = 'amd_64' | 'x86_64' then
gcc -dumpspecs | sed 2s/m64:--64/!m64:--64/1p
fi
else # Not OpenSolaris' uname
if 'uname -m' = 'i386' then
gcc -dumpspecs | sed 2s/m32:--32/!m32:--32/1p
fi
if 'uname -m' = 'amd_64' | 'x86_64' then
gcc -dumpspecs | sed 2s/m64:--64/!m64:--64/1p
fi
