[Buildroot] preserve toolchain

[Marcus Osdoba]

  Hello mailinglist,

For a shorter development cycle I like to preserve the toolchain 
generated by buildroot for the next run. I naivly copied the 
output/toolchain to some other directory and set the toolchain directory 
in the buildroot config. The bin-directory does not include the 
gcc-binaries. Do I have to create links in the bin-directory to the gccs?

Is it possible to take the same toolchain for package build the next 
time? Can I recycle the toolchain generated by buildroot?

Thanks for any reply.

Regards,
Marcus
