Compiling world or kernel with '-Os' is not supported.  Here is the 
CFLAGS comment in /usr/share/examples/etc/make.conf:
"CFLAGS controls the compiler settings used when compiling C code.  Note 
that optimization settings other than -O and -O2 are not recommended or 
supported for compiling the world or the kernel - please revert any 
nonstandard optimization settings to -O or -O2 before submitting bug 
reports without patches to the developers."

In this case, I would recommend removing the CFLAGS entry from 
/etc/make.conf (to get the default settings of "-O2 -fno-strict-aliasing 
-pipe") and adding the following line to /etc/make.conf:

CPUTYPE?=pentiumpro

This will automatically add "-march=pentiumpro" to your CFLAGS.
