Allow [big_or_little_endian] in ld's run_dump_tests

[Richard Sandiford <richard at codesourcery dot com>]

Some linker test procedures (such as run_ld_link_tests) automatically
add the endianness option for the current multilib.  It would be useful
to have a way of injecting the endianness option into run_dump_test
tests too.  The patch below does this by replacing the string
"[big_or_little_endian]" with the Tcl value of that expression.

We can then fix the only difference in mips-wrs-vxworks results
between no-endianness runs and -EL runs.  vxworks1-static.d is
a check-for-error run_dump_test that relies on objects created
by earlier run_ld_link_tests.  The earlier objects are created
with the multilib endianness option, so vxworks1-static.d should
use that same option.

Tested on mips-wrs-vxworks.  OK to install?
