PulseAudio looks for 32-bit libs and fails to find 64-bit variants

[rinigus]

Some libs are not loaded as 32-bit versions were found first. As a result, 64-bit version is not checked. Not sure if it matters, but logging here anyway.

Extract from strace (see below for more)

strace for PA attached

HYBRIS_LD_LIBRARY_PATH=/vendor/lib64:/vendor/lib64/hw strace -f pulseaudio -n --file=/etc/pulse/arm_droid_default.pa > logs/pa.strace 2>&1

shows that HYBRIS path was not effective
