Eskil Abrahamsen Blomfeldt 0fa5310425 Android: Enable -fno-builtin-memmove in arm builds
On some devices, a miscompilation of libc.so has caused it to
return the wrong value. Instead of returning the dest pointer,
it returns dest + n. When compiling with optimizations turned
on, gcc may use this return value for subsequent accesses to
dest after the memmove() call, causing memory corruption.

This caused problems e.g. in QVector::prepend() which would
overwrite the whole vector with the new value.

Setting -fno-builtin-memmove disables the optimization and
works around this bug with very little risk or impact.
