libgcc comes from gcc of course. It's a tricky one also because gcc is 
surely something you wont want on flash.
Now depending on the device/arch in question sometimes libgcc.so is 
needed by every single application.
I think the ideal way to work around this one for you will be something 
like touching the file /etc/portage/root_install_mask and slowly keep 
adding everything (glob*) in that file which is not the library in 
question.

Also. because you have busybox installed you should not need to add the 
additional gzip/bzip2/tinylogin as bb can and does provide all of that 
functionality as well.

good luck.
