Subject: [PATCH] main: Fix __iwd_backtrace_init() availability detection

Check for HAVE_EXECINFO_H for all __iwd_backtrace_init usages.

Fixes:

  src/main.o: In function `main':
  main.c:(.text.startup+0x798): undefined reference to `__iwd_backtrace_init'
  collect2: error: ld returned 1 exit status
