Locale support added the following issue with the android build:

jni/../../fmt-3.0.0/fmt/format.h: In member function 'void fmt::BasicWriter<Char>::write_int(T, Spec)':
jni/../../fmt-3.0.0/fmt/format.h:2756:45: error: 'struct lconv' has no member named 'thousands_sep'
fmt::StringRef sep = std::localeconv()->thousands_sep;
The problem is that in some implementation the lconv structed is just stubbed:
#if 1 /* MISSING FROM BIONIC - DEFINED TO MAKE libstdc++-v3 happy */
struct lconv { };
struct lconv *localeconv(void);
#endif /* MISSING */
However, c++ api exists, and everything compiles after the patch: https://gist.github.com/dpantele/d2e2aec8ff23b0208245c8a6e882f7fe
A haven't checked if it works though, because I am not an android dev.
