dev-cpp/gtest: Fix test failure on sparc64
sparc64 exhibits the same usersandbox stack overflow bug and its stack can apparently grow upwards in memory. Revert back to allocating 10 pages of mapped memory for the offending call to clone(). Bug: https://bugs.gentoo.org/692464 Reported-by: Rolf Eike Beer <gentoo-bug@opensource.sf-tec.de> Package-Manager: Portage-2.3.71, Repoman-2.3.17 Signed-off-by: Peter Levine <plevine457@gmail.com> Signed-off-by: Joonas Niilola <juippis@gentoo.org>
