branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
When building host gcc, patches stored in global patches directories are
skipped. This patch fixes the unexpected behavior.

[Thomas:
- rename the loop variable from 'D' to 'patchdir'
- add some additional comments
- remove final ; at end of loop when applying the patches, since it's
not needed]
