crosstool configure confusion re __cxa_atexit


I'm not sure whether this is from vanilla crosstool or Carl's uclibc 
patches, but I notice that configure was told to both disable and enable 
__cxa_atexit. That doesn't seem wise to me:

[charlieb@pc-00085 gcc-3.3.2-uClibc-0.9.23]$ cat build-gcc/config.status
#!/bin/sh
