When calling getenv_f() with a too small buffer, it would print an error message like this:

env_buf too small [32]

This is not really helpful as it does not give any indication which of the calls might have failed. Change this into:

env_buf [32 bytes] too small for value of "hwconfig"

so we know at least which variable caused the overflow; this usually allows to quickly find the related code as well.
