The Buildbot user has SHELL set to /bin/nologin to avoid giving the user
SSH access.  I'll change the SHELL environment variable to /bin/bash
when I start the Buildbot slave to avoid breaking the testing.

When I rebuilt this morning, I was running as the same user as the
Buildbot uses.  Also, I had SHELL set to /bin/bash.  I've just re-run
the build with SHELL explicitly set on the make command like:
make -j1 all SHELL=/bin/bash
make check RUNTESTFLAGS='gdb.mi/mi-watch.exp' SHELL=/bin/bash

I'm not seeing the messages:

Cannot exec $execfile -c exec $execfile

in any of the logs ("grep -i 'cannot.*exec' *" returns nothing).  I'm
attaching the build log from the above "make -j1 all SHELL=/bin/bash"
command above as build.log as well as the newer versions of the make
check and gdb.log logs.
