--- Comment #4 from jharjuma at gmail.com ---
I don't have any dynamic linker configuration files, eg. /etc/ld.so.conf,
/etc/ld.so.cache. In system search path /lib is before /usr/lib. libQt5Core.so
is installed in /lib/libQt5Core.so and /usr/lib/libQt5Core.so. Relocatable Qt
determines PrefixPath by going up towards root from the directory of the loaded
libQt5Core and chooses directory that contains 'lib' as PrefixPath
If Qt is non-relocatable, value of -prefix config switch is used as PrefixPath.
qtdiag reports correct PrefixPath if it is forced to use
/usr/lib/libQt5Core.so. Should buildroot configure qt as non-relocatable?

LD_LIBRARY_PATH=/usr/lib qtdiag --no-gl
