From: Yann E. MORIN Date: Wed, 22 Jun 2016 19:07:25 +0000 (+0200) Subject: package/skeleton: respect variables namespace X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=faece0a4259eecaec08af2ce43e4334f3fd1e6c3;p=buildroot.git package/skeleton: respect variables namespace In makefiles, variables have global scope. We traditionally ensure that we get no name clashing by prefixing all variables with the package name. Currently, this is not the case in the skeleton package, for historical reasons (code snippets copied over from the common Makefiles). We currently have a mix of naming for the variables: - some are indeed prefixed with SKELETON_ - some are prefixed with SYSTEM_ - some are prefixed with both - some are not prefixed Clean up these discrepancies, and prefix all variables with just SKELETON_ and drop the SYSTEM_ prefix. Also include SET_ in all variables that do set something (getty) for consistency across all the variables. Signed-off-by: "Yann E.
