According to this page [1], the current minimum version of gcc required to build Firefox trunk is 7.1.
If you need to build with gcc 5.4, you may need to build an older release or esr branch rather than current trunk. I don't know if the compiler requirements are documented on a per release basis anywhere, but searching dev-platform should allow you to get an idea of when the minimum required version was bumped.
