This reverts commit 6b0eb07886.
Per debian bug 896012 this is intentional behavior and a problem with
linitin. An additional commit will be added to ignore this lintian
error.
This is a workaround for what looks like a compiler bug introduced
in Debian and Ubuntu gcc-7.
After the compiler bug is sorted in Debian testing it should be
reverted.
Automake and autoconf are impossible to fully understand and Meson now provides
everything we need for a much smaller, faster, and more understandable build.
