devel/git: Fix build with PERL option disabled
configure.ac defines a macro (GIT_ARG_SET_PATH), which takes an optional
'allow-without' parameter, which if not specified (in configure.ac),
causes --without-foo/--with-foo=no not to be checked/allowed.
allow-without is set for python, but not for perl in configure.ac:
- Define PYTHON_PATH to provide path to Python.
- GIT_ARG_SET_PATH(python, allow-without)
- GIT_ARG_SET_PATH(perl)
The non-presence of the optional second macro argument results in the
following error when --without-perl is specified by
PERL_CONFIGURE_WITH=perl=${PERL}
configure:4065: error: You cannot use git without perl
This error is a regression after r427505 [1], which switched from
PERL_MAKE_ENV to PERL_CONFIGURE_WITH (and its associated --without-*).
This change adds:
- allow-without to configure.ac allowing --without-perl to work.
- USES=autoreconf to regenerate configure from configure.ac.
