ld: Extend ac_default_ld_warn_rwx_segments to all SPARC targets [PR29411]
As discussed in PR ld/29411, the ld warning
[...] has a LOAD segment with RWX permissions
needs to be disabled on all SPARC targets, not just Solaris/SPARC: the
.plt section is required to be RWX by the 32-bit SPARC ELF psABI and the
64-bit SPARC Compliance Definition 2.4.1. Given that ld only supports
SPARC ELF targets, this patch implements this.
Tested on sparc64-unknown-linux-gnu and sparc-sun-solaris2.11.
