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.
