2021-11-24Fix detection of ARMv7 and ARM64 CPU features on FreeBSDAllan Jude
OpenSSL assumes AT_HWCAP = 16 (as on Linux), but on FreeBSD AT_HWCAP = 25 Switch to using AT_HWCAP, and setting it to 16 if it is not defined. OpenSSL calls elf_auxv_info() with AT_CANARY which returns ENOENT resulting in all ARM acceleration features being disabled.

We received analytics that devices of the device family Oppo A37x are crashing with SIGILL when trying to load libcrypto.so. These crashes were fixed by using the system-supplied getauxval function.

2019-01-16crypto/armcap.c, crypto/ppccap.c: stricter use of getauxval()Richard Levitte
Having a weak getauxval() and only depending on GNU C without looking at the library we build against meant that it got picked up where not really expected. So we change this to check for the glibc version, and since we know it exists from that version, there's no real need to make it weak.
