Implement the --enable-targets= feature of the configure script. The make
variable TARGETS_TO_BUILD is used to determine which targets in lib/Target
are built and which libraries are linked into llc. This effectively
implements the feature. One item remains: disabling targets in the dejagnu
test suite.
