It explicitly tests for gawk since that is what the build says it
requires.

dnl OpenJDK's README-builds.html lists gawk as a build dependency so we
dnl check for it explicitly rather than using AC_PROG_AWK.
FIND_TOOL([GAWK], [gawk])

Yes, one is a compiler and one is a core class library set.

This really shouldn't be necessary anymore. At least not for
icedtea/jdk7, there might still be some header constants used in
icedtea6/openjdk6, but if so we should backport the fixes to remove them
and remove this check.
