x86, signals: fix xine & firefox bustage
Impact: fix bad frame in rt_sigreturn on 64-bit After commit 97286a2b64725aac2d584ddd1f94871f9991d5a1 some applications fail to return from signal handler: [ 145.150133] firefox[3250] bad frame in rt_sigreturn frame:00007f902b44eb28 ip:352e80b307 sp:7f902b44ef70 orax:ffffffffffffffff in libpthread-2.9.so[352e800000+17000] [ 665.519017] firefox[5420] bad frame in rt_sigreturn frame:00007faa8deaeb28 ip:352e80b307 sp:7faa8deaef70 orax:ffffffffffffffff in libpthread-2.9.so[352e800000+17000] The root cause is forgetting to keep 64 byte aligned value of fpstate for next stack pointer calculation.
