Adds the infrastructure to collect profiling information from Trusted
Applications running in user mode and instrumented with -pg.
Enable with: CFG_TA_GPROF_SUPPORT=y.
Profiling support in itself adds no significant performance overhead.
Instrumented applications however may run 1.3x - 2x slower, and have a
larger .bss section (+1.36 times .text size for 32-bit TAs, +1.77 times
.text size for 64-bit ones).
