Bug#901544: Make libwx-perl build reproducible

[=?UTF-8?Q?Br=C3=BCns at buxtehude.debian.org]

Package: libwx-perl
Version: 1:0.9932-4

libwx-perl build is still not reproducible.


Exported names are randomly vanishing/reappearing due to unstable build order, 
i.e. in /usr/lib/<arch>/perl5/5.26/Wx/Wx_Exp.pm
