[Buildroot] [git commit] pkg-generic.mk: strip leading/trailing spaces

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=2f0748578166a4717bbbb941cf768f4dca75e971
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The manual gives this example for using the github macro:

  FOO_VERSION = v1.0 # tag or full commit ID

Unfortunately, people copy/pasting this example will face weird make errors,
because it leads the FOO_VERSION variable to end with a space.  Similar
problems can happen when testing a version bump or similar, so strip
leading/trailing spaces before the version is used to construct the build
directory path.
