gcc49, illumos-gcc: preserve original tarball mtimes

otherwise for gcc49, we might end up running automake in mpfr/, which
will fail because mpfr-3.1.3 uses AM_AUTOMAKE_VERSION 1.15 and we have
1.15.1, and there is no aclocal call to update aclocal.m4.

for illumos-gcc, do the same for consistency.
