Subject: Config.mk: add new macro buildmakevars2header
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~4364
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=e8a23cfad48097c5ab78c05230ccc73ac183dfad;p=xen.git

Config.mk: add new macro buildmakevars2header

This macro is similar to buildmakevars2file, it just creates a C header
file instead of shell style syntax. Upcoming changes will use this macro
in libxl and libxc.
