Resolve compilation warnings on ARM
This MR aims to address warnings raised when compiling for ARM ( tested with cross compilation, not directly on ARM hardware ). The addressed warnings are as follows:
- An unused variable in file oai_dfts_neon.c
- Wrong printf format specifier related to oai_cputime_t
- Wrong parameter type in qam64_qam64 call
This MR closes issue #844 (closed)
Also, correctly set the pkg-config search path for libraries for the target system. Also closes: #746 (closed)
