[avr-libc-dev] build fails on x86_64 GNU/Linux, missing stddef.h

I successfully built 1.4.4 on an i386 GNU/Linux Fedora 4 system, but when
I attempt the same build on my x86_64 GNU/Linux CentOS 4.3(RHEL clone), I
get the error shown below.

ln gcrt1.o crttn861.o || cp gcrt1.o crttn861.o
make[5]: Leaving directory 
make[5]: Entering directory

It seems that my x86_64-hosted avr-gcc configuration isn't quite
correct.  avr-gcc wants to look under /usr/lib for include files, but my
avr-gcc configuration put the files under /usr/lib64.  Can someone give
me a hint as to the proper configuration?  For a cross compiler setup 
such as this, should the files be under /usr/lib or /usr/lib64?  What
configuration option controls this?
