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.
