enlightenment: bump to 0.17.3

Do not include <execinfo.h> when not available

On uClibc, <execinfo.h> is not necessarily installed, depending on the

configuration. Enlightenment properly makes <execinfo.h> optional, but

uses __GLIBC__ to check if it is available or not. Unfortunately,

uClibc defines __GLIBC__, so it is not the right way to decide if

<execinfo.h> is available.

Instead, Enlightenment already has a configure.ac check for

execinfo.h, so we simply use the result of this configure.ac check to

decide whether execinfo.h is to be included or not.
