looks like Maksim was right; the new fix does not do the second attempt to detect python libs, it finds it correctly with the first attempt

explained reason why IPP is disabled on 32-bit Linux. disable IPP's minMaxLoc_32f on 32-bit OSes only

2) disable IPP on 32-bit Linux when OpenCV is built as shared libs. Otherwise we get linker errors
3) disable IPP's minMaxIdx 32-bit floating-point flavor in a hope that it fixes some test failures
