Update `readelf' symbol table dump match patterns to handle SHN_MIPS_DATA
and SHN_MIPS_TEXT special section indexes produced by the IRIX ELF format
variation used with a number of MIPS targets and printed by `readelf' as
PRC[0xff02] and PRC[0xff01] respectively, correcting LD test suite
failures:
extra regexps in .../ld/testsuite/ld-elf/comm-data1.sd starting with "^ +[0-9]+: +[0-9a-f]+ +0 +OBJECT +GLOBAL +DEFAULT +[0-9]+ +foo$"
EOF from dump.out

observed due to file contents like:
7: 5ffe02e8 0 OBJECT GLOBAL DEFAULT PRC[0xff02] foo
shown by `readelf -s' vs:
+[0-9]+: +[0-9a-f]+ +0 +OBJECT +GLOBAL +DEFAULT +[0-9]+ +foo
pattern expected, triggered by widening testing to these targets by commit
05a5feafdd ("Rewrite check_shared_lib_support").
