Work around array out of bounds warning in mkdeps
This suppresses an array out of bounds warning in mkdeps.c as proposed
by Martin Sebor in the bugzilla.
array subscript 2 is outside array bounds of ‘const char [2]’
Since this warning does occur during bootstrap it currently breaks
werror builds on IBM Z.
The problem can be reproduced also on x86_64 by changing the inlining
threshold using: --param max-inline-insns-auto=80
Bootstrapped and regression tested on x86_64 and IBM Z.

* mkdeps.c (deps_add_default_target): Avoid calling apply_vpath to
suppress an array out of bounds warning.
