[PATCH 0/4] Fix issue with PROVIDE in linker scripts

[Andrew Burgess]

This series works is really all about patch #3, that fixes an issue in
linker scripts where PROVIDE can override a "normal" symbol.  The
issue is described in more detail in patch #3.

The other patches #1, #3, and #4, are all setup and cleanup.

I've tested this whole series against a set of 245 targets, there are
no new regressions.
