[Bug-readline] readline does not pick up first ld in PATH

[Stewart, Adam James]

Hi,

I'm working on the development of a package manager called Spack. One of the nice things about Spack is that it uses compiler wrappers to automatically add things like "-L/path/to/dependency/lib -I/path/to/dependency/include -Wl,rpath..." to the link line. This works for most packages, but doesn't seem to work for readline. Despite the fact that our ld wrapper comes first in the PATH, the readline build seems to pick up /Library/Developer/CommandLineTools/usr/bin/ld anyway. I can't figure out how to tell it to use our ld wrapper instead.

This in on macOS Sierra 10.12.4 with clang 8.1.0 and readline 7.0. Let me know if you need any other information. Thanks for your help!
