Minor clean-up to gas's mips.exp

[Richard Sandiford <r dot sandiford at redhat dot com>]

{[istarget mips*el-*-*]? "el":""} seems to crop up a lot in mips.exp.  I'm
about to submit a new reloc case, so is it OK to install the following
first?  Tested on mips-elf and mipsel-elf.

2001-07-25  Richard Sandiford  <rsandifo@redhat.com>

	* gas/mips/mips.exp (el): New variable.  Use it to decide which ELF
	reloc tests to run.
