configure: Don't check LD -v --help for LIBC_LINKER_FEATURE
When LIBC_LINKER_FEATURE is used to check a linker option with the equal
sign, it will likely fail because the LD -v --help output may look like
`-z lam-report=[none|warning|error]` while the needle is something like
`-z lam-report=warning`.
The LD -v --help filter doesn't save much time, so just remove it.
(cherry picked from commit 8438135d3481853e300e1043cfee3946dadb28b3)
