There seems to be a bug with the eglibc recipe as noted in a previous 
discussion [1] where pthreads requires libgcc.so to be available but it 
isn't pulled in as a requirement. Now, I believe this goes largly 
unnoticed as there are very few functions which actually require the 
libgcc.so lib, but it happens that one of the functions I use 
(pthread_cancel), does require it, so I run into this bug and as such 
have to depened on RDEPENDS = "libgcc" in order to ensure it is in the 
rootfs.

In the next version of the library I think I am going to see if I can 
work round using pthread_cancel in favour of a less awkward function.

Cheers,
Jack.
