Re: RPI: * failed to add service - already in use?

Similar issue with SDL2, this time on the latest 8.0_BETA:

Reading symbols from emulationstation...(no debugging symbols found)...done.
(gdb) run
Starting program: /usr/pkg/bin/emulationstation

Program received signal SIGILL, Illegal instruction.
0x72bb7ae0 in _armv7_neon_probe () from /usr/lib/libcrypto.so.12
(gdb)

That function only gets called here in armv4cpuid.S
(I have applied your diff)

#if __ARM_MAX_ARCH__>=7
.arch   armv7-a
.fpu    neon

.align  5
.global _armv7_neon_probe
.type   _armv7_neon_probe,%function
_armv7_neon_probe:
        vorr    q0,q0,q0
        RET
.size   _armv7_neon_probe,.-_armv7_neon_probe

.global _armv7_tick
.type   _armv7_tick,%function
_armv7_tick:
        mrrc    p15,1,r0,r1,c14         @ CNTVCT
        RET
.size   _armv7_tick,.-_armv7_tick
#endif

#if __ARM_MAX_ARCH__>=8
.global _armv8_aes_probe

__ARM_MAX_ARCH should be 6, not 7, since we are on armv6 and do not
have neon anyway.

I'll need to pick this up tomorrow now, but any ideas are welcome.
