Bugzilla Bug 37218

Every time I tried to emerge libao, it broke on what appeared to be the second
run of the ./configuration script, in the same spot every time (exiting with
`no error'). Forcing -j1 for my make options in `make.conf' fixed the problem,
so I am assuming the package does not like parallel makes.

Reproducible: Always
Steps to Reproduce:
1. emerge libao, version 0.8.4-r1, with the default make settings in
`make.conf'

Actual Results:  
Package breaks via die, with `no error' as the error given.

Expected Results:  
(1) The package should build
(2) The package should be a little more verbose as to why it failed to build ;)
