/* In the Linux kernel version 3.17, and glibc 2.21, 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.  */
