We had pbl_cc__o_c instead of pbl_cc_o_c. This caused all pbl object
files to be rebuilt everytime due to missing .cmd file.

This will allow to link compiled object to the built-in-pbl.o across the source
tree that will be finally link to the pbl.
Now we compile the source %.c in pbl-%.o and provide -D__PBL__
so we can known in the source when it's compile for barebox or the pbl.

When building sandbox with ccache, one would hit warnings such as:
warning: 'struct mmsghdr' declared inside parameter list
on random files; a way to reproduce this issue is to build a simple
file doing just:
#include <sys/socket.h>
int main(void) {
return 0;
}
gcc -Wall -P -c -o foo foo.c
But actually the -P flag is only useful when generating non-C files,
such as linker scripts in the case of barebox. Removing the -P flag
from all the gcc invocations, except when generating .lds files makes
the warning go away. It turns out that this is what
linux/scripts/Makefile.build also does nowadays.
