commit: http://git.buildroot.net/buildroot/commit/?id=e32c29a09849b71cb20c964880b9be671132b7b5
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master
In 9229b82d6326ea425a258b91a9f0157ef6b223b7 ('libcurl: needs MMU'),
the libcurl package was disabled on non-MMU systems, due to the usage
of the fork() function in the library.
However, a deeper inspection reveals that fork() is only used in the
implementation of NTLM, an obscure, undocumented, Microsoft specific
authentication method that apparently isn't common anymore. See
http://curl.haxx.se/docs/manpage.html#--ntlm.
Therefore, this commit re-enables libcurl on non-MMU systems by
explicitly disabling the NTLM support. If someone ever needs NTLM
support in Buildroot's libcurl package, it will always be time to add
a libcurl sub-option to enable it.
