# GCC (at least up to version 9.2) appears to emit function calls that make use
# of the GOT when targeting microMIPS, which we can't use in the VDSO due to
# the lack of relocations. As such, we disable the VDSO for microMIPS builds.

MIPS: VDSO: Move disabling the VDSO logic to Kconfig After commit 9553d16fa671 ("init/kconfig: Add LD_VERSION Kconfig"), we have access to GNU ld's version at configuration time. As a result, we can make it clearer under what configuration circumstances the MIPS VDSO needs to be disabled. This is a prerequisite for getting rid of 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'.

MIPS: remove CONFIG_MIPS_LD_CAN_LINK_VDSO Given commit e4412739472b ("Documentation: raise minimum supported version of binutils to 2.25"), CONFIG_MIPS_LD_CAN_LINK_VDSO is always 'y'.
