HPUX has a different .comm syntax, and anything in the first column
is a label.
gas/
* testsuite/gas/elf/strtab.s: Don't put directives on first
column or continuation with labels not in first column.
ld/
* testsuite/ld-elf/elf.exp: Xfail pr20995 tests on hppa64-hpux.
Set up HPUX defsym. Run pr14170 tests and build symbol3 objects,
defining HPUX where necessary. Define HPUX for implib tests.
* testsuite/ld-elf/comm-data4.d: Run for hpux.
* testsuite/ld-elf/endsym.d: Likewise.
* testsuite/ld-elf/linkoncerdiff.d: Likewise.
* testsuite/ld-elf/comm-data4.s: Add alternate .comm when HPUX.

* testsuite/ld-elf/symbol3.s: Likewise.
* testsuite/ld-elf/implib.s: Likewise. Don't start directives
in first column.
* testsuite/ld-elf/linkoncerdiff2.s: Don't use numeric labels.
* testsuite/ld-elf/warn3.d: Run for hpux.
* testsuite/ld-scripts/rgn-at10.d: Xfail for hpux.
* testsuite/ld-scripts/rgn-at11.d: Likewise.

* testsuite/lib/ld-lib.exp (run_ld_link_tests): Add optional
parameter to pass list of xfails.
* testsuite/ld-elf/elf.exp: Add xfails for implib tests. Tidy
implib test formatting. Don't set .data start address.
* testsuite/ld-elf/implib.s: Remove first .bss directive and
replace second one with equivalent .section directive.
