gdb: add patches to fix musl build on ppc(64)(le) and sh

This commit small patches to gdb that fix redefined structures build
problems that occur when building on PowerPC, PowerPC64, PowerPC64le and
SuperH with the musl C library.

The PowerPC(64)(le) patch was taken from the Yocto Project, the SuperH
patch was inspired from the PowerPC patch. The issue has also been
reported upstream to the musl developers:
