scripts/install-buildtools: add helper script to install buildtools
For distros such as CentOS-7 where the default buildtools are too
old we need to make it easy for users to install a pre-built SDK
with all of "build-essentials" included.
Other uses may include building older Yocto Project releases with
a distro where buildtools are too new.
For convenience, the standard buildtools installation is also
supported.
NOTE: extended buildtools is the default, e.g.
--with-extended-buildtools is on by default
Example usage (extended buildtools from milestone):
(1) using --url and --filename
$ install-buildtools \
--url http://downloads.yoctoproject.org/releases/yocto/milestones/yocto-3.1_M2/buildtools \
--filename x86_64-buildtools-extended-nativesdk-standalone-3.0+snapshot-
20200122.sh
(2) using --base-url, --release, --installer-version and --build-date
$ install-buildtools \
--base-url http://downloads.yoctoproject.org/releases/yocto \
--release yocto-3.1_M2 \
--install-version 3.0+snapshot
--build-date
202000122
Example usage (standard buildtools from release):
(3) using --url and --filename
$ install-buildtools --without-extended-buildtools \
--url http://downloads.yoctoproject.org/releases/yocto/yocto-3.0.2/buildtools \
--filename x86_64-buildtools-nativesdk-standalone-3.0.2.sh
(4) using --base-url, --release and --installer-version
$ install-buildtools --without-extended-buildtools \
--base-url http://downloads.yoctoproject.org/releases/yocto \
--release yocto-3.0.2 \
--install-version 3.0.2
