php: phpize: Modify ltmain.sh to support sysroot path in .la files

PHP's phpize is based on a very old libtool to generate build files for
its extensions. This libtool does not support .la files with '=' to
support sysroot.

In order to support more PHP extension cross compilation this modifies
ltmain.sh to support such path. This is a bit hackish has it only get
sysroot from the used toolchain; the proper way to fix that is to have
PHP developpers to update the autotools file used to build there
extensions.
