Well, before lto-wrapper was factored out of it, collect2 used to set
WPA_SAVE_LTRANS if -debug. lto1 uses this value way, way down the
cascade of stuff that happens on WPA "link", in order to suppress
removal of its temporary object files. Passing a command line flag
through this whole chain of events was deemed much too disruptive for a
So, setting WPA_SAVE_LTRANS if -debug needs to go back into collect2,
for lto1. Given that, isn't it simpler to just use this to retain
temporary files in the intermediate lto-wrapper, rather changing
collect2 to pass -debug to lto-wrapper?
