[Buildroot] Adding a ModemManager package

[Shawn J. Goff <shawn7400@gmail.com>]

I'm trying to add a ModemManager package. While building, I'm getting 
this error during the installation step: "/usr/lib/libgcc_s.so: file not 
recognized: File format not recognized". This looks like it's looking at 
my host's libgcc_s.so instead of the target's version. If that's the 
case I'm not sure why or how to fix it. I did have to use autogen.sh to 
create the configure script and lots of other stuff; I did this on my 
host system, so I'm not sure if that is affecting it.

Below is a larger part of the output for context.
