Re: [PATCH 1/4] Makefile: move "Platform specific tweaks" above LIB_{H,OBJS}

Change the Makefile so that the "Platform specific tweaks" section
comes before the assignments to LIB_H and LIB_OBJS.

In the ab/i18n series I only want to build gettext.o (by adding it to
LIB_OBJS) if NO_GETTEXT is unset. It's not possible to do that without
an ugly hack if we haven't applied our platform specific tweaks before
LIB_{H,OBJS} gets assigned to.

Isn't this similar to block-sha1, which is controlled by the feature macro
BLK_SHA1 that can be inferred from platform tweak?  The mechanism is not a
hack but is a way LIB_H and LIB_OBJS are intended to be used, so there
must be something missing in your explanation.
