* arm-linux-tdep.c (arm_linux_extract_return_value): Make static.

Browse source 
(arm_linux_push_arguments): Likewise.
(arm_linux_init_abi): Register them.  Also register linux-specific
call_dummy_words.
(find_minsym_and_objfile): Use strcmp, not STREQ.
* config/arm/tm-linux.h (CALL_DUMMY_WORDS): Delete.
(arm_linux_call_dummy_words): Delete declaration.
(EXTRACT_RETURN_VALUE, PUSH_ARGUMENTS): Delete.
(arm_linux_extract_return_value, arm_linux_push_arguments): Delete
declarations.
(LOWEST_PC): Delete.
