Excellent, thanks!

I come to think that a _DIR_SUFFIX for the patch-dir may
be needed also (if we have an occurrance in the tree already, that is.
No need to introduce this prematurely). I'm currently not aware of such
packages, though.

One nice example that, if it is handled properly by the autotools.in is
package/gmp or mpfr for that matter.

This package shows nicely what the autotools.in should provide in the
long run:
- downloading a PATCH_FILE to the dl/
- patching package/$name/$name$version
  or 
  patching package/$name/$version
  or 
  patching package/$name/$($(name)_patch_regex)
  or the like
- in configure, honor PREFERRED_LIB_FLAGS et al
- $(STRIP) the target, perhaps. Distinguish between binaries and libs
- optionally install headers if BR2_HAVE_HEADERS
- package-specific additional {C,LD,CPP,...}FLAGS
- package-specific additional configure-opts
- knowledge if both staging and target or only one of these should be
  populated with libs/binaries
