[Bug 825574] Re: cant compile native gcc /usr/include/linux/errno.h:4:23: fatal error: asm/errno.h: No such file or directory"

[youngsai]

Finally figured it out!

basically, /usr/include/asm  was renamed to /usr/include/asm-generic
and whoever did it was a snotty brat!

He only told half of the header files that he made the change!
the Half of the header files were looking but they couldn't find their friend...

Trying to tear apart the header files like that....  tsk tsk..

Sorry, I'm really high.
Basically, make a symlink from /usr/include/asm to /usr/include/asm-generic

It fixes everything.
Also I'm pretty sure that the problem lies in one of the multilib packages not creating this symlink.
probably gcc-multilib.  Or something.  Again, really high.
 
It shouldn't be a hard fix.

  make
