Turning on warnings in Automake makes it complain about not using the
AM_PROG_AR macro. The AM_PROG_AR macro is required when LIBRARIES or
LTLIBRARIES is used.

The macro looks for an archiver and wraps it in the ar-lib script which
is automatically generated so Git should ignore it.

It makes the custom check for 'ar' obsolete so it is removed.

The AM_PROG_AR macro was added in Automake 1.11.2 thus the minimum
Automake version is increased.
