Individual autoconf function broken out of acincludes.m4. This change per the recommended style guide for autoconf and so that individual autoconf functions can more easily be shared across projects. llvm-svn: 16223 2004-09-07 14:56:14 +08:00			`#`

This macro cannot assume that the location of install-sh and mkinstalldirs is in ${srcdir}/autoconf because that is only true if the project is LLVM. For other projects (e.g. sample), we don't want to have to distribute the mkinstalldirs or install-sh programs because it opens a window of breakage for projects. So, this change requires that the llvm_src variable be set up via another AC_CONFIG_COMMANDS call. For LLVM this is done in the configure.ac. For projects its done in the LLVM_CONFIG_PROJECT macro. llvm-svn: 20304 2005-02-25 02:28:20 +08:00			`[AC_CONFIG_COMMANDS($1,`
