[Buildroot] [PATCH v1] qt: fix postgresql plugin compile

[Peter Seiderer]

Add qt5base '-psql_config' configure option and use it to set
pg_config path in configure step instead of legacy PSQL_LIBS
enviornment variable.

Fixes [1]:

PostgreSQL support cannot be enabled due to functionality tests!
 Turn on verbose messaging (-v) to ./configure to see the final report.
 If you believe this message is in error you may use the continue
 switch (-continue) to ./configure to continue.
make: *** [/ssd1/thomas/autobuild/instance-0/output/build/qt-4.8.6/.stamp_configured] Error 101
