I have build error due missed crtfastmath.o from 5 series till 14 for Symbian. All crtfastmath.o usage declared in pair t-softfp and t-crtfm in libgcc/config.host, isn't it? The last one tells where to pick crtfastmath.o. Symbian share config with arm*-*-eabi and arm*-*-rtems. I checked this config many times and accidentally noticed that the t-crtfm unaviable. I remove t-softfp and error gone. Here that config: https://gcc.gnu.org/git?p=gcc.git;a=blob;f=libgcc/config.host;h=9fae51d4ce7dee206f5807bbdb2ce94ceeca33e9;hb=HEAD#l565 Stryzhniou Fiodar Стрижнёв Федор
