Subject: make: Change build to use our copy of avrlibc
X-Git-Tag: v1.6~33^2~1
X-Git-Url: https://git.htl-mechatronik.at/public/?a=commitdiff_plain;h=6555655b51bae688058ae3ab2b596ae79b2fbf90;p=sx%2Fsimavr.git

make: Change build to use our copy of avrlibc

Now uses our own copy, this should help build simavr with support for
all cores, on all hosts
