[uClibc]buildroot compile error

[Tony J. White]

I was able to get today's CVS of buildroot to compile on a rather slow
RedHat 7.3 machine.

After the toolchain was built, I tried continuing the build on my much faster
slackware-current machine and all was well up until gcc-target was being built.
At that point, configured died testing my C compiler.  The problem was:

/lib/crt1.o(.text+0x20): In function `_start':
: undefined reference to `__uClibc_start_main'
collect2: ld returned 1 exit status

Yes, my old friends crt*.o

Is it recommended to use gcc 2.96 for making buildroot, or are some people
having success with 3.2.1?
