New builds from the build-infra team

I finally have a clean build of
http://hg.openjdk.java.net/build-infra/jdk8 on Solaris 11.1 Sparc and
the times for a full build
are not too shabby:
00:00:34 corba
00:04:14 hotspot
00:00:29 jaxp
00:00:40 jaxws
00:03:19 jdk
00:00:38 langtools
00:09:54 TOTAL
The fix involves adding '-lc' to LDFLAGS for almost every native
library in CompileNativeLibraries.gmk. There may be a more elegant fix
but this one works for me...
