# What follows is a horribly cursed hack.

# GCC will install its libraries to $out/lib, $out/lib32, $out/lib64,
215
+
# $out/$targetConfig/lib, $out/$targetConfig/lib32 or $out/$targetConfig/lib64,
216
+
# depending on whether it's built as native or cross, and the exact target spec.
218
+
# We can't predict what it's actually going to do, and we also can't just tell it
219
+
# to always install to $out/lib, but we want everything to end up in $out/lib
220
+
# for consistency (multilib weirdness aside).
222
+
# So, we create a bunch of symlinks before we run GCC's install phase,
223
+
# redirecting every possible directory it may want to write to to the place
224
+
# we actually want things to be installed.
225
+
# We will then nuke the symlinks in postInstall.
227

# FIXME: there must be a better way to do this.
