    testsuite: Also exclude `*-*-kfreebsd*-gnu' from STB_GNU_UNIQUE tests
    
    Fix commit 02e0be69012a ("mbind gas tests and supports_gnu_osabi
    testsuite infrastructure") and also match `*-*-kfreebsd*-gnu' targets
    when determining whether STB_GNU_UNIQUE binding is supported for
    symbols.  These targets use the same BFD vectors as `*-*-freebsd*' do,
    choosing ELFOSABI_FREEBSD, and therefore need to be treated analogously.
    
    This fixes numerous regressions, e.g.:
    
    mips-kfreebsd-gnu  -FAIL: weaken STB_GNU_UNIQUE symbols
    mips-kfreebsd-gnu  -FAIL: strip on STB_GNU_UNIQUE
    mips-kfreebsd-gnu  -FAIL: diagnostics for visibility directives
    mips-kfreebsd-gnu  -FAIL: ld-unique/pr21529
    mips-kfreebsd-gnu  -FAIL: Linker setting GNU OSABI on STB_GNU_UNIQUE symbol (PR 10549)
    
    caused by the missing feature:
    
    .../gas/testsuite/gas/elf/visibility.s:14: Error: symbol type "gnu_unique_object" is supported only by GNU targets
