[U-Boot-Users] [patch] mkconfig crates bad symlink

[ito at mlb.co.jp]

Hello

mkconfig creates include/asm-*/arch.
but some board this symbolic link is broken and not necessary.
with this patch, mkconfig wil create a sym-link when there is a
directory to link.

CHANGELOG:

* mkconfig will not create broken symlink.
