I find it useful to see the commands during failing builds
(it started with samba, I also used this with proprietary products
at work).
I added an -E flag which overrides .SILENT and @<command>
to always echo the commands being done -- much better than running
strace or hacking up the makefiles...
It was so easy, I should have done it much sooner!!
(I've had this problem for more than a decade)!!
The patch is wrt 3.80, attached below:
