You are right glibc is LGPL. It's libstdc++ I was thinking of https://gcc.gnu.org/onlinedocs/libstdc++/manual/license.html

Looks like what I'm looking for can be found in MPLv2 https://www.mozilla.org/en-US/MPL/2.0/FAQ/

Ex: http://zeromq.org/area:licensing is currently LGPLw/exception, but intends to move to MPLv2 because it is legally more clear.
