Details - Currently, when running "make check" on a single package, it does not print any warning.  ''V=s'' is needed to see the warnings.  The build system should print the warnings in all cases, because that's what the user asks for!

To reproduce:


$ make package/nlbwmon/check 
 make[1] package/nlbwmon/check
 make[2] -C feeds/packages/net/nlbwmon check



$ make package/nlbwmon/check V=s
make[1]: Entering directory '/tmp/lede'
make[2]: Entering directory '/tmp/lede/feeds/packages/net/nlbwmon'
WARNING: nlbwmon-2017-08-02-32fc0925.tar.xz is missing, please run make download before re-running this check
make[2]: Leaving directory '/tmp/lede/feeds/packages/net/nlbwmon'
make[1]: Leaving directory '/tmp/lede'


The main target ''make check'' (without specifying any package) works fine, because it seems to run in verbose mode by default:


$ make check
make[3]: Entering directory '/tmp/lede/tools/gmp'
make[3]: Leaving directory '/tmp/lede/tools/gmp'
...
make[3]: Entering directory '/tmp/lede/package/network/utils/iwinfo'
WARNING: PKG_MIRROR_HASH is missing, set to 7bd294f50f8ec8c0497c5fbe5527f3ae098814cdfeecf4ccf78a2a8937611664
make[3]: Leaving directory '/tmp/lede/package/network/utils/iwinfo'
...


I tried to fix the issue myself but this is way above my understanding of make.
