Fix ignored --elf32-strip-target-libs

Options --[no-]elf32-strip-target-libs were ignored - instead behaviour was
to always strip libraries. That was happening because variable containing
option value hasn't been exported to invoked scripts.

Also change check from `!= no` to `= yes` for uniformity with other similar
checks.
