Subject: Make make output quieter (Avi Kivity)
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=4f188f88874830c1fdca6144938ac0db1cbc540a;p=qmiga%2Fqemu.git

Make make output quieter (Avi Kivity)

Spew out less noise when compiling.  This helps review make output for
information such as compilation warnings, rather than extra long compiler
invocations.

The full output can be generated by supplying a 'V=1' parameter to make.
