[PATCH 18/21] Fix failing test cases for linux and 64-bit target

[Milica Matic <milicamatic05@gmail.com>]

From: Faraz Shahbazker <fshahbazker@wavecomp.com>

Fixing tests for the MIPS architecture by adding a .space marker
to generate terminal sequences, updating test outputs, fixing
relocations, and enabling the use of 32-bit and 64-bit ABIs for
precise testing.

Cherry-picked 7abff2b

    * gas/testsuite/gas/mips/micromips.s: Add .space
    marker to generate terminal sequence.
    * gas/testsuite/gas/mips/micromipsr6@micromips.d: Update reference
    output to match.
    * gas/testsuite/gas/mips/llpscp-32-micromips.d: Set 32-bit ABI to
    enable building with 64-bit default tools.
    * gas/testsuite/gas/mips/llpscp-64-micromips.d: Fix relocations
    to be section relative and force the ABI to n32.
