[asterisk-bugs] [JIRA] Commented: (ASTERISK-20128) Virtualized asterisk.org 1.8.14.0 no longer runs in a KVM virtualized environment. Compiles without error, but fails with Illegal instruction on launch Regression since 1.8.13.0 Last good 1.8.12.2

Matt Jordan commented on ASTERISK-20128:
----------------------------------------

This was changed in the following revision:

* Makefile.rules, makeopts.in, codecs/lpc10/Makefile, Makefile,
          build_tools/cflags.xml, build_tools/menuselect-deps.in,
          codecs/gsm/src/k6opt.s, configure, codecs/gsm/Makefile,
          configure.ac: Simplify build system architecture optimization
          This change to the build system rips out any usage of PROC along
          with architecture-specific optimizations in favor of using
          -march=native where it is supported. This fixes broken builds on
          64bit Intel systems and results in better optimized code on
          systems running GCC 4.2+. Review:
          https://reviewboard.asterisk.org/r/1852/ (closes issue
          ASTERISK-19462)

You may need to disable the BUILD_NATIVE menuselect flag and - possibly - specify the architecture you wish to compile for using the CFLAGS environment variable.
