# Builds JBR21 for Intel Mac
# Usage:
#   build-jbr_next-mac-x64.sh [-q]
# The JDK is built in OUT_DIR (or "out" if unset).
# The following artifacts are created in DIST_DIR (or "out/dist" if unset):
#   jdk.zip              archive of the JDK distribution
#   jdk-debuginfo.zip    .debuginfo files for JDK's shared libraries
#   configure.log
#   build.log
# Specify -q to suppress most of the output noise
