MIPS/BFD: Account for VxWorks .got.plt references
On VxWorks calls can refer directly to a .got.plt entry, in which case
they won't have an entry in the regular GOT. It was missed with commit
6c42ddb92b90 ("MIPS GOT: Remove TLS GOT info from the symbol table"),
<https://inbox.sourceware.org/binutils/878v6uyaw3.fsf@talisman.default/>,
which revamped GOT entry bookkeeping, and consequently space for regular
GOT entries is needlessly reserved and then not used, with extraneous
null dynamic relocations attached, e.g.:
Relocation section '.rela.dyn' at offset 0x1400 contains 11 entries:
Offset Info Type Sym.Value Sym. Name + Addend
00080c0c 00000405 R_MIPS_HI16 00000000 __GOTT_BASE__ + 0

00081808 00000502 R_MIPS_32 00081808 dglobal + 0

00000000 00000000 R_MIPS_NONE 0
00000000 00000000 R_MIPS_NONE 0
Adjust regular GOT entry counting then to take .got.plt entries into
account, removing a regression from the commit referred:
mips-vxworks -FAIL: VxWorks shared library test 1
mipsel-vxworks -FAIL: VxWorks shared library test 1
