2d2dbd3024
The latest merge conflict resolution worked only for ARM, but not for x86
Both ARM and x86 builds have been tested with this fix.
Change-Id: I4ec1f1b0ea32fa86e7e2515b221133473d6550a3
NOTE: Care has been taken to not change the compiler flags for ARM builds.
In particular, when building crtbegin_so.so, the -fPIC flag is only
used for x86 (previous reports indicate that it breaks the ARM
build at runtime for obscure reasons).
