[llvm-commits] CVS: llvm/Makefile.common

[John Criswell]

Changes in directory llvm:

Makefile.common updated: 1.107 -> 1.108

---
Log message:

Reverted back to using OR for cmp/mv operations for lex/yacc output.
The shell AND/OR operators short-circuit on command success/failure, which is
the inverse of exit status (i.e. 0 means success, non-zero means failure).
