No, there's no reason to avoid the GPL for languages, because you aren't building a derivative work of the language itself, so it's licensing has no bearing on your software.
That's not entirely true; GCC (and almost every other GPL-licensed compiler) has a specific exception for its runtime libraries that lets you distribute their compiled version under any license [1].
But for example, Ada Core's GNAT is licensed under GPL but doesn't have that exception, which makes the binaries it outputs be licensed under the GPL as well, to make you buy the Pro version of the compiler.
