[bitbake-devel] [PATCH] data: escape '$' in shell variable assignment

[Richard Tollerton]

Running bitbake inside make results in the exported environment variable
MAKEOVERRIDES="${-*-command-variables-*-}", which the shell chokes on
when trying to expand it. But of course, it probably shouldn't have been
trying to expand it in the first place -- so just escape the dollar
sign.
