cpuflags defaults to '-march=native', which is only valid on x86 platforms.

Read the code:

 On a relatively clean 6.1.0 install, I find using cpuflags breaks
 (pkgsrc) build because of a seemingly unsupported "-march=native"
 flag.

 I noticed this issue while building lang/perl5 from pkgsrc 2013Q2, but
 I hope the above isolates the issue enough (i.e. it is not
 package-related).

 Toolchain issue IMO -- this flag is defined since gcc 4.2.
