ERL-1411: OTP master no longer builds on Alpine Linux

You probably know about this one but since I've not seen it reported...

Building OTP master on Alpine seems to have been broken sometimes in the past 2 weeks. This is the default build without any particular option. The environment:

Linux alpine0 4.19.107-xxxx-std-ipv6-64 #1154255 SMP Thu Mar 12 13:37:16 UTC 2020 x86_64 GNU/Linux

The following error is printed as of November 19 around 11am:

CC obj/x86_64-unknown-linux-gnu/opt/jit/sys_signal_stack.o
sys/unix/sys_signal_stack.c:169:2: error: #error "beamasm requires a libc that c
an guarantee that sigaltstack works"
 #error "beamasm requires a libc that can guarantee that sigaltstack works"
 ^~~~~

Of course Alpine is using musl, and perhaps it can't use the JIT as a result (for now, anyway), but I would expect it to produce a functional build nevertheless.

Thanks for your report! I've added a configure test that disables the native stack feature rather than the entire JIT:
