Thomas Monjalon 1cd512b2f5 build: detect execinfo library on Linux
The library execinfo and its header file can be installed on Alpine Linux
where the backtrace feature is not part of musl libc:
	apk add libexecinfo-dev

As a consequence, this library should not be restricted to BSD only.

At the same time, the library and header are detected once and added
globally to be linked with any application, internal or external.

Fixes: 9065b1fac6 ("build: fix dependency on execinfo for BSD meson builds")
