Welllll, you could use getenv("USER") and LOGNAME instead of
getpwuid(), or fork/exec/spawn id(1) to get the username. And you
could use a DNS library to resolve the hostname without the benefit of
local caching (unless there's a local caching server).
The bigger problem is that this is something you'd risk having to do
again and again every time something else in glibc ends up needing
dlopen(). It's a losing battle, and even if it isn't (maybe nothing
else in glibc will ever need dlopen()), philosophically it is a losing
battle. So you have to build an executable per-distro -- welcome to
Linux.
