Subject: Implement #64517: Add AC_ARG_PROGRAM macro
X-Git-Tag: php-7.4.0alpha1~2036

Implement #64517: Add AC_ARG_PROGRAM macro

The AC_ARG_PROGRAM Autoconf macro provides program name transformations
when installing. This patch implements #64517 and prepares the
implementation for the request #60518.

In ./configure --help it additionally outputs --program-prefix=PREFIX,
--program-suffix=SUFFIX and the upcoming --program-transform-name=PROGRAM
option.

Macro AC_ARG_PROGRAM is available since Autoconf 2.0 and needs to be
called after the AC_CANONICAL_TARGET macro.
