generate-prebuilts.sh

#
# This script is used to generate gnu_efi prebuilts for both ia32 and x86_64.
# The resulting binaries will be copied into prebuilts/{ia32, x86_64}.
#
# Please make sure you have Android's build system setup first, and lunch
# target defined.
#
# Specify "-a" in command line to add these prebuilt binaries for
# git commit.
#
# Note:
# 1. ARCH ia32 and x86 are interchangable here.
#    Android uses x86, but EFI uses ia32.
