Details:

It seems that in Gnu Make 4.0 (or thereabouts) the target

load : whatever

would attempt to load a shared object called ":" and issue a confusing error
message which looks rather like C++ "could not load:: file not found".  Given
that this a recent change in Gnu Make's behaviour (I was bitten by this on an
upgrade from LMDE betsy to Mint Selina), that "make load" is problematic as a
search term, and that make's own documentation used a space between the target
and colon until recently, that when attempting to load a shared object called
":" that a "are you sure that you don't have a space between the target 'load'
and the colon" message is issued.  Two lines on C and would be good UX.

Thanks

Jim
