scripts: remove obsolete gcc-ld script

Since commit 8564ed2b38 ("Kbuild, lto: Add a gcc-ld script to let run gcc
as ld") in 2014, there was not specific work on this the gcc-ld script
other than treewide clean-ups.

There are no users within the kernel tree, and probably no out-of-tree
users either, and there is no dedicated maintainer in MAINTAINERS.

Delete this obsolete gcc-ld script.
