Just add V=2 to make flags used for uclibc?

Still requires manually hacking some Makefile etc, since V=xx is tyoically given at cmdline once for entire build.

I found the terse output with just defines rather neat.
If there is consensus that the current V=1 has no benefit then we can drop it in favour of just silent 0 and fully verbose 1.


No, the idea is to keep both V=1 and V=2, but make them like other projects.
e.g. in kernel build, V=2 prints the single liners, while V=1 prints the verbose cmdline,
While in uClibc it's the other way around. Same with Busybox AFAIKR.

Simple patch below addresses that, please consider applying.

Subject: [PATCH] buildsys: Change build verbostiy behaviour V=n

Currently V=2 prints the verbose cmdline, anything else (say V=1) prints
the terse single liners. This doesn't match with other projects such as
kernel/busybox.

So change that by making V=1 print the verbose cmdline and others (say
V=2) to print the single liners.
