Subject: Makefile: don't run "rm" without any files
X-Git-Url: http://git.tremily.us/?p=git.git;a=commitdiff_plain;h=61564ca5bf29bb8039b865514a7593fc7b6c5440

Makefile: don't run "rm" without any files

When COMPUTE_HEADER_DEPENDENCIES is set to "auto" and the compiler
does not support it, $(dep_dirs) becomes empty.  "make clean" runs
"rm -rf $(dep_dirs)", which can fail in such a case.
