branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master
If ext-toolchain-wrapper was built with a gcc that uses hash-style 'gnu' by
default, the resulting binary might be unusable on other systems. The error
in this case is "Floating point exception".
Using hash-style 'both' solves this issue.
