Running 'make' twice triggers a gcc rebuild

[John H Palmieri]

Anyone seen this? On one OS X machine, with two different installations of Sage 6.9.rc0 (one built by upgrading earlier versions, one built from a fresh tarball), if I do this:

$ make distclean
$ make
$ make

then the second time, although it should do almost nothing, it rebuilds gcc. I recently upgraded from Xcode 7.0 to 7.0.1; could that cause it? Any other ideas of what might cause it?

Something similar happened to me on an x86_64 GNU/Linux machine where
the system version of GCC is 4.6.3. When typing "make" a second time
after upgrading to 6.9.rc0, it started reinstalling GCC; I don't know
what caused this, but prevented the rebuilding by simply doing "touch
local/var/lib/sage/installed/gcc-4.9.2.p1".

It must be the recent build system changes.
