kbuild: test --build-id linker flag by ld-option instead of cc-ldoption

'--build-id' is passed to $(LD), so it should be tested by 'ld-option'. This seems a kind of misconversion when ld-option was renamed to cc-ldoption. Commit f86fd30 ("kbuild: rename ld-option to cc-ldoption") renamed all instances of 'ld-option' to 'cc-ldoption'. Then, commit 691ef3e ("kbuild: introduce ld-option") re-added 'ld-option' as a new implementation. Signed-off-by: Masahiro Yamada <[email protected]>
