gcc calls dsymutil when it creates output without an intermediate object
file, when debugging is enabled.
e.g. gcc -g -o foo foo.c
will create foo and a "bundle" foo.dSYM.
This causes issues for autoconf when it does rm conftest* :)
Anyway, Ralf fixed it (rm -rf conftest*)! in git autoconf and GNU
libtool, so when autoconf-2.62 has been out for a while you'll see
fewer of these warnings.
Note that with autoconf-2.5.x generated configure scripts these are
probably just warnings, with autoconf-2.13 generated configure scripts
you'll probably get errors.
If you want them to go away - ./configure CFLAGS="-Os" (no debugging
symbols).
