After check all possibles post about this, I finally got a good compilation using a Linux x64 machine and Curl version 7.37.0 at path ${android-ndk-r10}.
Maybe this steps can help you:
1º
${android-ndk-r10}/build/tools/make-standalone-toolchain.sh --platform=android-15 --arch=armv7-a --toolchain=arm-linux-androideabi-4.8 --install-dir=./tmp/android-15
2º
export CC="${android-ndk-r10}/external/curl/tmp/android-15/bin/arm-linux-androideabi-gcc"
3º
./configure --host=arm-linux --enable-cross-compile --enable-threaded-resolver --disable-shared --disable-ftp --disable-file --disable-ldap --disable-ldaps --disable-rtsp --disable-dict --disable-telnet --disable-tftp --disable-pop3 --disable-imap --disable-smtp --disable-gopher --disable-manual --enable-proxy --enable-ipv6 --enable-cookies --enable-symbol-hiding --disable-versioned-symbols --disable-soname-bump --disable-sspi --disable-ntlm-wb --prefix=${android-ndk-r10}/external/curl/build/curl-7.37.0
4º
make -j4
5º
make install
You will get a build version at ${android-ndk-r10}/external/curl/build/curl-7.37.0.
If you are using a 64bits machine to compile, maybe 2 defines are bad, and you get this error:
error: size of array '__curl_rule_01__' is negative
I solve redefining the variables in file ${CurlbuildAndroid}/include/curl/curlbuild.h (Its dangerous to do this, but it worked!):
CURL_SIZEOF_LONG 4
CURL_TYPEOF_CURL_OFF_T 4
