Makefile: use phony targets

Add 'build', 'build-*', and 'install' as phony targets to the top level
Makefile.

I tend to do everything in tree with the build in a directory called
'build'. This interfered with the target 'build', making it think the
target was up to date, and stopping scripts/crosstool-NG.sh from being
regenerated.

Added 'install' as I often set the prefix to $PWD/install.

     3 I tried to use crosstool-ng to generate a toolchain for Linux on big

     4 endian arm with recent versions of gcc, glibc, etc... but had a few

     5 problems.

     7 It appears that the gcc patch (for gcc 4.2.x)

     8 for big-endian arm (240-arm-bigendian.patch) lacks the change attached

     9 to this mail as 240-arm-bigendian2.patch.
