package/libunwind: disable for x86 with uClibc toolchain
libunwind use sigreturn() while building for x86 [1] but this function is not available with uClibc-ng. This throw a warning during libunwind build: In file included from x86/Los-linux.c:4:0: x86/Gos-linux.c: In function ‘_ULx86_local_resume’: x86/Gos-linux.c:298:7: warning: implicit declaration of function ‘sigreturn’ [-Wimplicit-function-declaration] sigreturn (sc); ^ But any program trying to link against libunwind-generic.so fail to build: [...]usr/lib/libunwind-generic.so: undefined reference to `sigreturn' collect2: error: ld returned 1 exit status Disable libunwind for x86 target when uClibc-ng is used.
