The root cause is that now beignet will build internal binary kernels according current build host's
Gen VGA PCI id. It need lspic command to get the pci id but your system doesn't have lspci installed.
I just submitted a patch to do this check before we enter the real compiling stage. You may need
to check which package contains lspci in your system and install it before build beignet.
