There would be an race issue if we:
$ bitbake make-3.81 make-3.82
This because they are being built at the same time which would cause
unexpected problems, for example:
[snip]
ERROR: Package already staged (/path/to/tmp/sstate-control/manifest-qemux86-make.populate-sysroot)?!
ERROR: Function failed: sstate_task_postfunc
[snip]
Or there would be python's strack trace such as:
[snip]
*** 0004: mfile = open(manifest)
0005: entries = mfile.readlines()
0006: mfile.close()
0007:
0008: for entry in entries:
Exception: IOError: [Errno 2] No such file or directory: xxx
[snip]
[YOCTO #5094]
We can quit earlier to avoid this kind of issue when two versions of the same PN
are going to be built since this isn't supported.
