            Bug ID: 214513
           Summary: devel/linux_libusb: gcc provided by CentOS is too old
                    to understand some valid CPUTYPE
           Product: Ports & Packages
           Version: Latest
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: Individual Port(s)
          Assignee: emulation@FreeBSD.org

I set CPUTYPE=3Dcorei7 in /etc/make.conf, and the value is converted to
-march=3Dnehalem by Makefiles installed on FreeBSD 11.0-RELEASE. CentOS 6 u=
ses
gcc 4.4 and CentOS 7 uses gcc 4.8, but this option is only supported on gcc=
 >=3D
4.9, which can cause build failure for devel/linux_libusb. This problem also
happens in native FreeBSD gcc (gcc 4.8) and a bug (bug 214173) is already f=
iled
for the native port.
