[PATCH][PINGx2] fix PR43602 for emutls targets

[Jack Howarth]

  Currently emutls is not being properly finalized
as was exposed when the profiling race conditions
fix (r157822) was applied to gcc trunk. Can we get
a review for Iain Sandoe's fix...

that will clear the way for the profiling race conditions
fix to be re-applied to gcc trunk? Thanks in advance.
