* In interactive mode (-I2), those signals that were blocked at startup
will remain blocked for the whole period of strace execution.
* When traced command is terminated by a blocked signal, strace unblocks
that signal to ensure its own termination with the same signal.
* Fixed corner cases in decoding of old sigaction syscall.
+ * Fixed build with old kernel headers on mips.
+ * Fixed build on aarch64 and tile with glibc >= 2.26.

===============================================
==============
* Fix Linux/ia64 support, looks like someone renamed a few things on us
* Fix the ioctl setup for Linux, turned out it did not really work.
- Improve the ioctl extracter as well so we decode some more ones.
