Remove this legacy hack and just use
f the MIPS VDSO binutils
warning and linking the VDSO when LD is ld.lld. Wrapping the call to
ld-ifversion with CONFIG_LD_IS_LLD does not work because the config
values are wiped away during 'make clean'.

Hi all,
This series allows ld.lld to properly and completely link the MIPS vDSO.
Patch 1 adds ld.lld support to Kconfig so that we can avoid certain
ld.bfd checks.
Patch 2 moves disabling of the VDSO to Kconfig. This allows us to avoid
a warning with LD=ld.lld during the clean phase, when we do
