Hello Harold,
I'm not sure ARMv6 has the possibility to typedef a __uint128_t, which would make compiling your openssl with --enable-ec_nistp_64_gcc_128 impossible.
I have nothing to back up those claims however, it is just a hunch. Someone else should confirm, if he/she has better knowledge.
Regards,
Martin

There are three equally plausible scenarios: Your compiler doesn't support 128-bit unsigned integers; your compiler does support them, but OpenSSL is being compiled with the wrong command-line options, so they're disabled; or the actual source code is making assumptions about _how to get at the 128-bit unsigned integer type_ which are incorrect.
I don't know which scenario you're in, but I can help you find out. Look through the compilation logs for openssl and find out the exact set of command-line options given to gcc to compile ecp_nistp224.c. Then, using the same set of options, except replacing -c with -S and removing '-o whatever.o' if present, compile this test program:
typedef unsigned int __attribute__((mode(TI))) uint128_t; const __SIZE_TYPE__ n = sizeof(uint128_t);
If this fails to compile, post the command line and the *unedited* error messages. If it compiles successfully, post the command line and the *unedited* .s file.
