FYI this issue was temporarily fixed by specifying --disable-shared in
the top-level configure...after running make distclean.
Unfortunately the build fails again soon after libgcc, when
configuring libstdc++, with thw following error:
configure[11845]: awk not found
configure: error: Link tests are not allowed after GCC_NO_EXECUTABLE
I'm using gawk and have AWK=/bin/gawk.
