Subject: [PATCH] Disable ltcg for host_build

debug-prefix-map does not work correctly for static libraries
when using ltcg, and since host_build compilations link agaist
the libQt5Bootstrap.a library, it breaks source file packaging
into debug packages.

Task-number: QTBUG-71230
Upstream-Status: Inappropriate [embedded specific]
