Subject: Forward abort calls to Unikraft's UK_CRASH
X-Git-Tag: RELEASE-0.13.0~12
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=3d279ddb1ab2390f55070d165d66f7aa162871ba;p=unikraft%2Flibs%2Fmusl.git

Forward abort calls to Unikraft's UK_CRASH

The signals are currently ignored and that causes musl to `exit` the
thread, which doesn't cause any output. Therefore, it's very unclear
what happened. By calling `UK_CRASH` there is a clear indication that
something went wrong.
