I spotted that jsig is just a single C file and so doesn't
need the -std flag. In fact, it complains about it:

Compiling jsig.c (for libjsig.so)
( ( /usr/bin/gcc -fPIC -D_GNU_SOURCE -D_REENTRANT -O2 -pipe -march=core2 -std=gnu++98 -m64 -g -DTHIS_FILE='"jsig.c"' -c -MMD -\

.log && exit $exitcode ) ) && wait )
cc1: warning: command line option '-std=gnu++98' is valid for C++/ObjC++ but not for C

So just ADLC is fixed now.

The root webrev is the same as before.
