This is sad as it makes debugging seccomp filter policies impossible on some architectures (at least ARM and PowerPC, maybe also others) which do not coincidentally set si_value.sival_int as the syscall number. To fix this, import the definitions and macros needed from glibc.

When attempting to build uClibc under buildroot, including building the tests, the silly tests don't currently compile, a result of attempting to build using a compiler that does not yet have an installed version of uClibc available. The error is a missing header file, specifically atomic.h. Taking inspiration from the nptl tests, I have extended the EXTRA_CFLAGS variable to add the required include paths. The tests can now be built under buildroot.

The current code implements the 'm' modifier only for 's' conversions and would cause a segfault if it was used for 'c' or '[' conversions. This patch extends the code to cover these cases too. The original version could write scanned data outside the passed buffer because index i used in the '[' conversion handling block was clobbered.
