Syntax: $0 [ -l <libc> -a <arch> -t <tests> ]

Explanation:
	-l: c library to use (uclibc-ng|musl|glibc|uclibc)
	-g: use latest git version of C library
	-a: architecture to check (otherwise all supported)
	-u: update openadk source via git pull, before building
	-s: use directory with source for C library
	-d: enable debug output from OpenADK
	-c: clean OpenADK build directory before build
	-n: set NTP server for test run
	-t: run tests (boot|libc|ltp|native)
	-p: add extra packages to build
	-r: rebuild C library
	-m: start a shell in Qemu system for manual testing
