[Buildroot] strace-4.8

[Chris Zankel]

Hi,

With strace-4.8 just released, we can probably now enable the package
for aarch64(?), arc, and xtensa :-)

I don't have a patch ready (yet), as there are two patches in the strace
package I'm not sure are still necessary:

strace-fix-arm-bad-syscall.patch - add fix for ARM fake syscall from
execve. Closes #626
strace-fix-disabled-largefile-syscalls.patch - bump version and make it
behave of LFS is of

Thanks,
-Chris
