Does your platform provide PThread interface? If yes, which macro could

This seems to be as the threadapi was not set to pthread.

I see that you have set the <threadapi>pthread but I don't know if the 
bjam syntax is correct here

   toolset.add-requirements <toolset>gcc-ppc:<target-os>elf 
<toolset>gcc-ppc:<threadapi>pthread

What is toolset.add-requirements?

Have you tried just with

   <target-os>elf <threadapi>pthread

or remove this line and try on the  CLI with

bjam -d+2 toolset=gcc-ppc target-os=elf threadapi=pthread 
-sGCC_ROOT_DIRECTORY=C:\Xilinx\ISE_DS\EDK\gnu\powerpc-eabi\nt64\bin 
link=static --layout=system --with-thread

Please, could you provide the result of the build when -d +2, in 
particular the calls to the compiler and the linker if the preceding 
doesn't works?

Best,
Vicente
