gcc: xtensa: fix __builtin_frame_address use with shared libgcc
The xtensa port uses __xtensa_libgcc_window_spill in libgcc to implement
__builtin_frame_address. This symbol is local/hidden in libgcc. This is not a
problem when linking against static libgcc. But g++ defaults to
-shared-libgcc, thus breaking link against C++ shared libraries that are using
__builtin_frame_address as follows:
ld: test: hidden symbol `__xtensa_libgcc_window_spill' in .../libgcc.a(lib2funcs.o) is referenced by DSO
Add upstream patches that make libgcc_s.so a linker script that links in
unresolved symbols from the static libgcc, similar to the ARM and PowerPC
ports.
