Subject: disable the brk function
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=863d628d93ea341b6a32661a1654320ce69f6a07;p=musl

disable the brk function

the reasons are the same as for sbrk. unlike sbrk, there is no safe
usage because brk does not return any useful information, so it should
just fail unconditionally.
