In usr.bin/make/var.c, function ParseModifier(), initialize the 'error'

variable to NULL, to avoid using it uninitialized in certain cases.

This fixes the following clang 3.2 warning:

  usr.bin/make/var.c:1770:10: error: variable 'error' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized]
                                          if (vp->execute) {
                                              ^~~~~~~~~~~
  usr.bin/make/var.c:1777:10: note: uninitialized use occurs here
                                          if (error)
                                              ^~~~~
  usr.bin/make/var.c:1770:6: note: remove the 'if' if its condition is always true
                                          if (vp->execute) {
                                          ^~~~~~~~~~~~~~~~~
  usr.bin/make/var.c:1768:23: note: initialize the variable 'error' to silence this warning
                                          const char      *error;
                                                                ^
                                                                 = NULL
