In order to build a gcc for a newlib target with a working libgcov,
you need build from a unified source tree and configure using
--with-headers --with-newlib.
Using current mainline sources, when configuring with:
../srcw/configure --target=sh-elf --with-headers --with-newlib
the compiler fails to build with:
mv tmp-specs specs
