hppa: Make __SIGRTMIN 32 (ABI break).
In the Linux kernel version 3.17 the signal numbers were rearranged in order to make hppa like every other arch. Previously we started __SIGRTMIN at 37, and that meant several pieces of important software, including systemd, would fail to build. To support systemd we removed SIGEMT and SIGLOST, and rearranged the others according to expected values. This is technically an ABI incompatible change, but because zero applications use SIGSTKFLT, SIGXCPU, SIGXFSZ and SIGSYS nothing broke. Nothing uses SIGEMT and SIGLOST, and they were present for HPUX compatibility which is no longer supported. Thus because nothing breaks we don't do any compatibility work here. Upstream kernel commit is 1f25df2eff5b25f52c139d3ff31bc883eee9a0ab.
