MIPS/GAS: Treat local jump relocs the same no matter if REL or RELA
Do not convert jump relocs against local MIPS16 or microMIPS symbols to
refer to a section symbol instead even on RELA targets, as it makes it
impossible for the linker to make a JAL to JALX conversion based on ISA
symbol annotation, breaking regular and compressed MIPS interlinking.

* config/tc-mips.c (mips_fix_adjustable): Also return 0 for
jump relocations against MIPS16 or microMIPS symbols on RELA
targets.
* testsuite/gas/mips/jalx-local.d: New test.
* testsuite/gas/mips/jalx-local-n32.d: New test.
* testsuite/gas/mips/jalx-local-n64.d: New test.
* testsuite/gas/mips/jalx-local.s: New test source.
* testsuite/gas/mips/mips.exp: Run the new tests.

* testsuite/ld-mips-elf/jalx-local.d: New test.
