I came into this problem not only with newlib-1.10 but also when trying
to build the second stage gcc. It died in the libiberty directory. That
was with gcc-2.95.3. It seems to be a gcc problem with the m68k-coff
target. I ended up with patching gcc to install a spec file, a crt0.o
and a linker script that are more or less dummies but link without
errors. You may look into the crossgcc mailing list, also on
sources.redhat.com.
