Subject: [PATCH] tools/lib/api: allow the linker to be overridden

Makefile in lib/api unconditionally sets the LD to support
cross-compilation. However, when invoked from within the perf build LD
may be already appropriately set for a given platform and the override
may lead to cross-compilation without appropriate linker flags.

Change the unconditional override to a conditional one.

Fixes: 37b4e2020a5f ('perf build: Add EXTRA_LDFLAGS option to makefile')
Fixes: 703e01652d25 ('tools lib api: Respect CROSS_COMPILE for the linker')
