toolchain-external: Introduce kernel headers sanitization
The Nios-II Sourcery external toolchain (the only Nios-II we currently
support) exports broken kernel headers. In particular, these kernels should
be exported using the "headers_install" rule which applies a set of fixes
on the kernel headers so they are suitable for userspace usage.
In order to fix this, add a post-install hook to perform the header fixes
ourselves. The result is equivalent to apply the "headers_install" rule.
Fixes:
