Although that's clever, it is a gratuitous source-code incompatibility with BSD,
which is not a good thing. To some extent it's just GLOB_FOLLOW and
GLOB_NOFOLLOW in disguise, and disguise is not a good thing in APIs. So I think
I still prefer the compat symbol approach.
We'll get GNU 'Make' fixed, and I wouldn't worry overly much about people
building unpatched 'Make' with new glibc. I filed a Make bug report is here:
