makepkg: move build enviroment set-up to function

Browse Source 
This is a requirement to split the preparation of the build environment
into libmakepkg, which will allow dropping in extensions (e.g. to allow PGO).

After this patch, disabling buildflags or makeflags and enabling debug
CFLAGS will only effect the build(), check() and package() functions.  The
relevant variables are no longer exported for the prepare() function.  This
should have zero impact for the prepare() function of a properly written
PKGBUILD, as no building/linking is done there...
