bitbake-buildall simplifies the process of build testing an upgraded or
patched recipe by cycling through the build steps for each available qemu
target, with desired LIBC specified by the user as an option (defaulting
to both glibc and musl if no option is provided). While building, a log
file with the name "<recipe>-buildall.log" is written, containing a PASS
or FAIL line upon completion of the build for each architecture. For now,
qemu targets are not selectable (i.e. the recipe is built for all qemu
targets found in meta/conf/machine), but this functionality can be added
in the future along with other useful options.

The log file created by bitbake-buildall also includes some basic system
info (e.g. build start time, hostname, host OS, host kernel). Since it is
not guaranteed that tools such as lsb_release will be available on the
host (it isn't by default on my Fedora machine), this information is
collected manually. Additionally, the previous run's log is retained for
comparison by renaming it in the format <recipe>-buildall.log.old once a
new set of builds is triggered for the same recipe.

Finally, in v2, the line "set -o pipefail" has been removed to be fully
POSIX-compatible.

Sample log output:

if its building qemu machines only, then naming it build-qemuall.sh or
some such would be
better, I would avoid usine bitbake- prefix. That can confuse with bitbake tools

The intent is that it can be extended to machines other than just qemu with later patches, so I'm hesitant to give it a qemu-specific name.

I could rename it to something like buildall-targets.
