Without it, programs using .init sections will just segfault. The
workaround comes from http://www.openssl.org/~appro/values.c
Tested on 5.10, not needed on 5.11.
Of particular note is this package contains gfortran which is required
for building some scientific software (recent versions of scilab
for example). Package is prepared as a monolithic install of gcc
since gcc is really not set up to build and install the core and then
later add on different languages as their own packages.
