[Buildroot] Known good x86-64 host/target configuration with dev tools?

[Buildroot] Known good x86-64 host/target configuration with dev tools?

[Scott Moore]

Hi,

I've been trying for some time to build a chroot jail for compiling code 
against uclibc on a x86_64 platform without worrying about contamination 
from the system glibc, etc. To do this, I've been trying to use 
buildroot with development files on the target and gcc/make/etc packages 
enabled. I keep running into problems with the resulting target 
toolchain, though. With NPTL support on, all executables compiled by my 
target gcc segfault. With linuxthreads instead, I still encounter what 
appear to be mis-compiles (though could be bugs in the code I'm compiling).

Since I'm not confident in my configuration, I was wondering if anyone 
has a known good buildroot/uClibc configuration that targets x86_64 with 
a target toolchain with C++ support.

Thanks,
Scott
