/* 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. */
