[mm-common] Only show commands actually executed by make

[Daniel Elstner <daniel src gnome org>]

commit 3c1db29e6108f085b29335a4f1bece94057e4205

    Only show commands actually executed by make
    
    * Makefile.am (tags/libstdc++.tag): Use $(if ...) construct to handle
    the condition at the make level, instead of using shell conditionals.
    This way, the make output only displays the command that was actually
    executed.
    (.DELETE_ON_ERROR): Enable delete-on-error mode for reliability.
    * configure.ac (AM_INIT_AUTOMAKE): Add -Wno-portability to suppress
    warnings about GNU make extensions being used.
