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. libcpp/ChangeLog: 2020-01-16 Andreas Krebbel <krebbel@linux.ibm.com> PR tree-optimization/92176 * mkdeps.c (deps_add_default_target): Avoid calling apply_vpath to suppress an array out of bounds warning.
