Description Alpha Bravo 2016-05-09 11:39:58 UTC 
dev-qt/qtwebengine-5.6.0 grsec: denied RWX mmap of <anonymous mapping> by /usr/lib64/qt5/libexec/QtWebEngineProcess

leads to segfault at runtime (tested with www-client/qupzilla-2.0.0: loading websites is impossible).

Paxmarking m /usr/lib64/qt5/libexec/QtWebEngineProcess on hardened solves this problem.

A patch to qtwebengine-5.7.0.ebuild

This adopts how it's done in www-client/chromium: first buiild and paxmark mksnapshot (bug #579712) to be able to build the rest, then paxmark QtWebEngineProcess.
