LD: Fix .startof.SECNAME/.sizeof.SECNAME tests for MIPS/IRIX Correct .startof.SECNAME/.sizeof.SECNAME tests for MIPS/IRIX targets, complementing commit dc74becf498f ("ld: Add tests for -Ur") and commit da614360f520 ("ld: Add tests for .startof.SECNAME/.sizeof.SECNAME") with subsequent updates, and in reference to commit cbd0eecf261c ("Always define referenced __start_SECNAME/__stop_SECNAME") and commit 7dba9362c172 ("Rewrite __start and __stop symbol handling"). These targets set the STT_OBJECT type for non-function symbol references, according to `elf_frob_symbol' code in gas/config/obj-elf.c: /* The Irix 5 and 6 assemblers set the type of any common symbol and any undefined non-function symbol to STT_OBJECT. We try to be compatible, since newer Irix 5 and 6 linkers care.
