I don't think that the Objective-C support in Buildroot is widely used
and tested. Therefore, if you don't need it, I would suggest to disable
it (disable the option named ?Build/install Objective-C compiler and
runtime??. You can also probably do the same with Java and Fortran if
you don't need the support for those languages.

Sincerly,

Thomas
