Build failure for ARM/thumb with the most recent snapshot

Hi!

The most recent snapshot of newlib - 2.5.0.20170720 - fails to build
for ARM "default" architecture ARMv4 with -mthumb:

The problem seems to be fixed in the repository just one day after it
was introduced:

Maybe it would be possible to "nuke" this snapshot and just have
another one?
