[lvm-devel] [PATCH 04/15] configure.in: Add dummy pkg-config initialization

[Fabio M. Di Nitto]

PKG_CHECK_MODULES macro is expanded to initialize the pkg-config
environment only at the first invokation.
In our configure.in all PKG_CHECK_MODULES are/will be conditionals.

This change will make sure to init the enviroment properly and
only if required.
