dlb doesn't compile with clang

[Alessandro Barbieri]

If you try to compile dlb with clang, you get this errors:

clang-12clang-12clang-12: : error: clang-12error: error: : no such file or directory: './.libs/libdlb.so': errorno such file or directory: './.libs/libdlb.so'

Sorry, I cannot reproduce the error. I'm using the same configure line as in your logs except for CC=clang, since it's not my default, and CFLAGS="-Wno-error" because there was an unwanted warning at that version that is already fixed in master. And the compilation succeeds.

> clang --version

Your error suggests that is something related to the build system. Can you run either ./boostrap or autoreconf -fi before the configure step?

Let's close for now, I've re tried and I can't reproduce
