LD/testsuite: Conditionalize the placement of `.got' in GNU_RELRO
Complement commit d345186d0535 ("Check if GNU_RELRO segment is is generated") and exclude the presence of a `.got' section from implying the creation of a GNU_RELRO segment for targets which place the section along with small data, and therefore as it stands cannot have the section assigned to GNU_RELRO. This is because we currently only support a single GNU_RELRO segment and we place it at the beginning of regular data which is then separated from small data by read-write data. Currently the list of such targets consists of Alpha, Linux HPPA, NetBSD HPPA, OpenBSD HPPA, Meta, MIPS, Nios II, OpenRISC 1000, RISC-V, SH and X86-64, as determined by examining default linker scripts produced in a `--enable-targets=all' build for those that have DATA_SEGMENT_RELRO_END set and `.got' placed beyond. These targets do not set NO_SMALL_DATA or DATA_GOT in their respective files in ld/emulparams/*, hovever checking for the absence of these settings on its own is not very feasible due to the structure of these files and the lack of support for GNU_RELRO by some targets in the first place. Add a separate control for `.got.plt' which does get placed in GNU_RELRO on MIPS targets even though `.got' does not. ld/ * testsuite/ld-elf/binutils.exp (binutils_test): Make the expectation for `.got' in GNU_RELRO segment target-specific. Handle `.got.plt' separately.
