Due to -nostdinc switch in default CPPFLAGS compiling of OS dependent files in
'sandbox' architecture may miss some required search paths.
Therefore remove -nostdinc for os dependent files in 'sandbox'.
Without this patch something like this may occour:
---8<---
In file included from /usr/include/fcntl.h:27:0,
from os.c:22:
/usr/include/features.h:323:26: fatal error: bits/predefs.h: No such file or
directory
