A little bit off topic, but thats OK.
To check the size of an variable type, configure compiles and runs
a small program. Since you're compiling for arm-linux, obviously you
can't run that program on your host system.
The best way to fix that is to add this:
ac_cv_sizeof_char=${ac_cv_sizeof_char=1}
to the config.cache file in the same directory you are running
configure in.
Odds are you will probably need one of these too:
ac_cv_sizeof_wchar_t=${ac_cv_sizeof_wchar_t=1}
ac_cv_sizeof_unsigned_char=${ac_cv_sizeof_unsigned_char=1}
ac_cv_sizeof_bool=${ac_cv_sizeof_bool=1}
ac_cv_sizeof_int=${ac_cv_sizeof_int=4}
ac_cv_sizeof_long=${ac_cv_sizeof_long=4}
ac_cv_sizeof_long_int=${ac_cv_sizeof_long_int=4}
ac_cv_sizeof_long_long=${ac_cv_sizeof_long_long=8}
ac_cv_sizeof_short=${ac_cv_sizeof_short=2}
ac_cv_sizeof_short_int=${ac_cv_sizeof_short_int=2}
ac_cv_sizeof_size_t=${ac_cv_sizeof_size_t=4}
ac_cv_sizeof_void_p=${ac_cv_sizeof_void_p=4}
ac_cv_sizeof_float=${ac_cv_sizeof_float=4}
ac_cv_sizeof_double=${ac_cv_sizeof_double=8}
ac_cv_sizeof_long_double=${ac_cv_sizeof_long_double=8}
ac_cv_sizeof_unsigned_short=${ac_cv_sizeof_unsigned_short=2}
ac_cv_sizeof_unsigned_int=${ac_cv_sizeof_unsigned_int=4}
ac_cv_sizeof_unsigned_long=${ac_cv_sizeof_unsigned_long=4}
ac_cv_sizeof_unsigned_long_long=${ac_cv_sizeof_unsigned_long_long=8}
ac_cv_sizeof_signed_char=${ac_cv_sizeof_signed_char=1}
