Disable string merging with alignment > 1 before Solaris 11.4/SPARC
* configure.ac (gcc_cv_ld_aligned_shf_merge): New test.
* configure: Regenerate.
* config.in: Regenerate.
* varasm.c (mergeable_string_section): Use readonly_data_section
if linker doesn't support SHF_MERGE with alignment > 8.
(mergeable_constant_section): Likewise.
