ld: Extend ac_default_ld_warn_rwx_segments to all SPARC targets [PR29…

…411] 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. 2022-07-28 Rainer Orth <[email protected]> ld: PR ld/29411 * configure.tgt (ac_default_ld_warn_rwx_segments): Extend to all sparc targets.
