Description:

perl-config-simple (4.59-5) sets a _builddir variable using ${srcdir}, but does so outside of a build function. Thus it is evaluated before makepkg sets srcdir, and when the package later attempts to cd to $_distdir it tries to change to an incorrect directory directly under root. Unless the behaviour of makepkg changed recently, I've no idea how this ever built.

Steps to reproduce:

Try to build perl-config-simple.
