One of the more curious bugs, if you use
-Wl,-headerpad_max_install_names on linux, it tries to link a library
named "eaderpath_max_install_names" in, which causes all kinds of weird
havoc.
Most notably, gtester inside glib fails to run for bizarre reasons.
-Wl,-headerpad_max_install_names is not an option anywhere outside macos
anyway, so move it to macos only and avoid the heartache of extremely
weild bugs.
