x32 Fast tracepoints: IPA target descriptions
Building GDB for x32 fails building the IPA, with:
.../src/gdb/gdbserver/linux-amd64-ipa.c: In function const target_desc* get_ipa_tdesc(int):
.../src/gdb/gdbserver/linux-amd64-ipa.c:182:14: error: tdesc_amd64_avx_linux was not declared in this scope
return tdesc_amd64_avx_linux;
^
.../src/gdb/gdbserver/linux-amd64-ipa.c:184:14: error: tdesc_amd64_mpx_linux was not declared in this scope
return tdesc_amd64_mpx_linux;
^
.../src/gdb/gdbserver/linux-amd64-ipa.c:186:14: error: tdesc_amd64_avx_mpx_linux was not declared in this scope
return tdesc_amd64_avx_mpx_linux;
^
[...]
The problem is that the IPA is trying to use the 64-bit descriptions,
when it should be using the x32 ones.
