dd803a2430 Testsuite fixes for hppa64-hpux 
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/comm-data5.s: Likewise.
	* testsuite/ld-elf/endsym.s: Likewise.
	* testsuite/ld-elf/pr14170c.s: Likewise.
	* 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/ld-scripts/size-2.d: Remove xfail for hpux.

5df1bc570f Fix implib test failures 
bfd/
	* elf.c (_bfd_elf_filter_global_symbols): Skip local symbols.
	(swap_out_syms): Return an error when not finding ELF output
	section rather than asserting.
	* elflink.c (elf_output_implib): Call bfd_set_error on no symbols.
ld/
	* 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.
	* testsuite/ld-elf/empty-implib.out: Add expected final error.
	* testsuite/ld-elf/implib.rd: Update.
