qpkg: Makefile cleanup and added OpenWRT target

Browse Source 
- Makefile: added automatic dependenceies (needs SHELL = /bin/bash)
- Makefile: added non-verbose builds
- Makefile (jlime): set CC_normal instead of CC, so that also cross-builds
  can be non-verbose
- Makefile (openwrt): new target to cross-compile for OpenWRT with uClibc
- Makefile (spotless): added "spotless" target
- gobble.c: uClibc may not have posix_madvise, so replace it with a dummy
  if building for uClibc
