#     Revert "kbuild: Check if linker supports the -X option"
#     
#     This reverts commit d79a27195a33f4b5e591de5536799ad874ea6cf5.
#     
#     According to the commit description, this ld-option test was added for
#     the gold linker at that time.
#     
#     Commit 75959d44f9dc ("kbuild: Fail if gold linker is detected") gave
#     up the gold linker support after all.
#     
#     I tested the BFD linker from binutils 2.23 and LLD from LLVM 11.0.0.
#     Both of them support the -X option.
