The gengtype patch we apply to gcc aims to ensure that the build and host
config headers don't get confused. We're seeing build failures where
both headers have been included, likely due to a race over the configuration
files.

It seems the gengtype-lex.c file isn't being regenerated when it should
and the unconditional inclusion of bconfig.h is resulting in these issues.

The fix is therefore to remove the file, forcing its regeneration.

[YOCTO #6393]
