Same with samtools.

Edited libs/bcftools/Makefile and libs/samtools/Makefile to remove the flag and it compiled.

Thanks @rec3141. This is discussed on the bcftools issues page: samtools/bcftools#388

I'm not sure how best to fix this. I'd rather not maintain my own fork of bcftools just to fix this compilation issue. Hopefully the samtools team can provide a fix. In the meantime, you have to remove the -rdynamic flags manually from libs/bcftools/Makefile and libs/samtools/Makefile.

Is this still an issue?
