hmm, that looks similar to how the structure is when you download the
NDK from Google:
http://developer.android.com/tools/sdk/ndk/index.html
but at least for the original one from above link it turned out for me
that it is not directly usable but instead you have to create the
'standalone toolchain' with the provided script
./build/tools/make-standalone-toolchain.sh
see http://curl.haxx.se/docs/install.html (or .docs/INSTALL in libcurl
source reee).

you mean the Android.mk in libcurl source tree? Then sorry, I cant
comment on this one since I never used it; but if you wait a bit I'm
sure that Dan will comment on this ...

yes, looks good; and permission error is because of insufficient rights
which is normal if you want to install stuff into '/usr/local/lib' as
non-root; and good that you were stopped by this since that doesnt sound
for the right location! As I said before you should use --prefix, f.e.:
--prefix=/tmp/curl-7.x.y-android-devel
or something like that.

these look unusual, and I assume either your NDK version is strange
here, or again this is an issue because of not having created the
standalone toolchain.

thats even more strange:
1) although it seems you did build everything fine above, now you build
again here
2)even more strange that you try to build curl although you shouldnt
need it since you're after the lib only for linking your jni, or?
3) this build seems to use either a handcrafted or a wrong curl_config.h
- configure detects if `getpass_r' is available or not and sets a define
in curl_config.h acordingly.

since we see that you use above a wrong curl_config.h which was not
properly created by configure then certainly these errors are of same
reason.

that doesnt matter since a static lib has its dependencies as well, and
these are *not* resolved at creation time, but you need to provide the
dependend libs finally when the app (or jni) is linked.

1) lets wait what Dan says about Android.mk if you prefer this way.
2) I might later build a version since I anyway want to test something -
but that will be from GIT repo, and is not an official release! This I
can provide to you.
3) you can provide your jni, and if I find some time I can try to build
it (but might last few days ...)
