Can you try without CPUTYPE "native", or with another value ?
"native" is not a supported value in /usr/share/mk/bsd.cpu.mk
With gcc I used :
CPUTYPE?=core2
CFLAGS=-O2 -pipe -march=native
NO_CPU_CFLAGS=yes
COPTFLAGS=-O2 -pipe -march=native
NO_CPU_COPTFLAGS=yes
So that /usr/share/mk/bsd.cpu.mk could set the right variables and I
could set my own "-march" value in CFLAGS for gcc.
But now for HEAD (which has a newer gcc and clang) I use :
CPUTYPE?=core2
CFLAGS=-O2 -pipe -march=core2
NO_CPU_CFLAGS=yes
COPTFLAGS=-O2 -pipe -march=core2
NO_CPU_COPTFLAGS=yes
Because with clang, -march=native often breaks buildworld, while
-march=core2 is ok.
First, try to see if you buildworld is still broken with a different
(or empty!) make.conf.
