Description:
------------
./Configure --with-pear=/usr/local/php/pear is not working correct. The optinal parameter is not set in the Makefile. 
Because this the PEAR files are always installed in the default location ($PREFIX/lib/php).

When I changed the following line in the Makefile from PEAR_INSTALLDIR = ${exec_prefix}/lib/php to
PEAR_INSTALLDIR = /usr/local/php/pear
the files and the pear.ini (file locations) files are correctly installed.

Expected result:
----------------
Pear files should be installed in /usr/local/php/pear

Actual result:
--------------
Pear files are installed in $PREFIX/lib/php
