• Install: take into account the --build, --host, --target, --enable-dependency-tracking and --disable-dependency-tracking configure options to transmit them to the configure scripts of Modules Tcl extension library and Modules compatibility version. (fix issue #354)
• Install: ignore some regular options of an Autoconf configure script that are useless for this project but usually implied in build macros (like RPM %configure macro).
• Install: ignore unsupported --enable-* and --with-* options on configure script rather raise an error and add support to define environment variable and build system type as configure script arguments to comply with GNU configuration recommendations.
• Install: fix modulecmd pre-alternatives check in RPM spec file.
• Install: use %make_build and %make_install macros in RPM spec file.
• When module switch command is used in modulefile, do not state when processing it a conflict over switched-off module if its specification on the module switch command also matches switched-on module's specification. Allow this way the replacement of any loaded version of a module for a specific one required by currently loading module. (fix issue #355)
• Correctly report failed attempts to load module requirements expressed with advanced version specifiers. (fix issue #356)
