Indeed.  We=E2=80=99d just need to add a parameter to =E2=80=98make-ld-wrap=
per=E2=80=99 so we
can specify the executable name, which would be =E2=80=9Cgold=E2=80=9D inst=
ead of =E2=80=9Cld=E2=80=9D
in this case.

Would you like to give it a try?

LIBRARY_PATH is honored by gcc, which =E2=80=9Cconverts=E2=80=9D it into a =
list of -L
flags for the linker, so no worries here.

HTH, and sorry for the delay!
