But as I stated already, this needs an ld switch to enable/disable ordinal
linking and allow limiting of used libs or path

for example

--enable-ordinal-link[=path1[,path2]]

	enable ordinal linking for given path/files or unlimited ordinal linking if no
path is given.

--disable-ordinal-link[=path1[,path2]]

	disable ordinal linking for the following path/files
