* Bump to 7.49.1 and call runConfigure with CFLAGS=_BSD_SOURCE and
CXXFLAGS=-D_BSD_SOURCE otherwise "make check" fails to build.
* Drop $manDir/man3 on 2nd arch devel packages.
* Move the manual page of curl-config(1) to the devel package.
* Use install (instead of mkdir and cp) to simplify INSTALL().
* Keep $binDir for 2nd arch since x86_gcc2 fails many tests.
* No need to call libtoolize. Keep autoconf (needed on x86_64).
* Add version info in rdef file to have "Get Info" show it.
