Define a new special type: buildopts.

This allows build flags to be specified for a particular program from
within the crunch.conf file, eg:

	prog ppp
	special ppp buildopts -DNOKLDLOAD -DNOINET6 -DNONAT -DNOATM

This adds '-DNOKLDLOAD -DNOINET6 -DNONAT -DNOATM' to make targets
related to ppp when determining which object files to build and
when calculating dependencies and building the targets.
