ld testsuite alpha_ld_flags

This is how alpha can use -Ttext-segment on just those tests that need
it.  And since the way run_dump_test uses $opts(ld) allows tcl procs to
be embedded, there is no need to specially expand [big_or_little_endian].

binutils/
	* testsuite/lib/binutils-common.exp (run_dump_test <opts(ld)>): No
	need to handle big_or_little_endian specially.
ld/
	* testsuite/ld-elf/elf.exp (alpha_ld_flags): New proc.
	(LDFLAGS): Don't set -Ttext-segment for alpha globally.
	* testsuite/ld-elf/compress1a.d: Add alpha_ld_flags.
	* testsuite/ld-elf/compressed1a.d: Likewise.
	* testsuite/ld-elf/eh5.d: Likewise.
