Log Message:
make(1): do not export variable names starting with '-'
By convention, names of environment variables consist of uppercase
letters and underscores. Most of them start with an uppercase letter.
In a few cases, the names also contain lowercase letters, such as in
http_proxy.
Variable names starting with a hyphen are confusing and might be
mistaken as command line options. Therefore don't export these.
This also affects a few edge cases that don't occur in practice, such as
setting .MAKE.EXPORTED=-env or .MAKE.EXPORTED=-literal. These had not
worked as expected anyway.
