Subject: [PATCH] src: unbreak build when compiling against uclibc

It seems that it is possible with some toolchains for both `__GLIBC__`
and `__UCLIBC__` to be defined, confusing our "do we have execinfo.h?"
logic.

Assume that when `__UCLIBC__` is defined, we are dealing with a libc
that does not have execinfo.h.
