[aur-requests] [PRQ#5520] Deletion Request for gcc49

[notify at aur.archlinux.org]

nsdfyd [1] filed a deletion request for gcc49 [2]:

make: *** x86_64-pc-linux-gnu/libstdc++-v3/doc: No such file or
directory.  Stop.
==> ERROR: A failure occurred in build().
    Aborting...

echo $CHOST

nothing...
So how to change this var or what to do?
