[patch/rfc] force linker hash style in linker tests

[Mike Frysinger <vapier at gentoo dot org>]

many linker tests rely on sysv being the default (and only) hash style due to
either different symbol behavior (linker bug 11355) or symbol ordering.  so
force the default hash style since this is what everyone tests against and
what the test output expects.

perhaps the better way to address this is declare a global linker flag
variable and stick these things there ?  there doesnt seem to be an example
for me to piggy back off of in the linker test framework ...

	* lib/ld-lib.exp (default_ld_relocate): Add --hash-style=sysv.
	(default_ld_link): Likewise.
	(default_ld_simple_link): Likewise.
