misc cleanups

Hi,

A bunch of individual (separate) touch-ups. They are only numbered so i can easily keep track.

I've split the arch selection improvements into 2 parts as requested by Peter and at the end of the series, the _nofpu/_nommu suffix is dropped.

Peter, please apply or pull from my config-cleanup branch TIA,
Bernhard

Bernhard Reutner-Fischer (14):
allow menuconfig without a LINUX26_KCONFIG file Allow for specifying kernel version manually handle MMU configuration
expand arch selection
remove superfluous OPTIMIZE and DEBUG config knobs allow for testing gcc-4.5
*-menuconfig needs dirs to exist
remove BR2_FPU_SUFFIX
tidy up ROOTFS_{PRE,SUF}FIX handling
honour DISABLE_IPV6
disable-locale implies turning off locale and iconv
rsync: bump version
enable config.cache per default
libpcap, tcpdump: bump version and autotoolify
