Indeed.  We’d just need to add a parameter to ‘make-ld-wrapper’ so we
can specify the executable name, which would be “gold” instead of “ld”
in this case.

Would you like to give it a try?

LIBRARY_PATH is honored by gcc, which “converts” it into a list of -L
flags for the linker, so no worries here.

HTH, and sorry for the delay!
