Verification problem on tb72?

[David Ostrovsky]

There seem to be a prolem with tb72, e.g.
on verification of this change: [1],[2]:

make[2]: ***
[C:/cygwin/home/tdf/lode/jenkins/workspace/lo_gerrit/Config/windows_msc
_dbgutil_32/external/lcms2/ExternalProject_lcms2.mk:19:

make: *** [C:/cygwin//home/tdf/lode/bin/cygwrapper.Makefile:6: all]
Error 2
Build step 'Execute shell' marked build as failure
Finished: FAILURE

I am not able to reproduce it here, and even on anoter TB, a next
change: [3], that depends on [1], can be verified without any issue,
however on tb78: [4].

To avoid annoying false negatives, can we please fix tb72 or take it
downm unless the problem is tracked down, isolated, reproduced and
fixed?
