Modified Files:
        src/external/gpl3/gcc.old/dist/gcc/config/m68k: t-floatlib
        src/external/gpl3/gcc.old/lib/libgcc/arch: m68k.mk

Log Message:
Tweak LIB1ASMFUNCS order to avoid linker warnings on libgcc_s build with -O2.

Without this change, ld complains as the following:
>> libgcc_s_pic.a(_float.pico):(.text+0x8): relocation truncated to fit:
>> R_68K_PC16 against symbol `$_exception_handler' defined in .text section in
>> libgcc_s_pic.a(_floatex.pico)

_float.S and _double.S refer `$_exception_handler' declared in _floatex.S
and linking the _floatex.S first seems to work around these warnings
(probably caused by pic relative jump addresses).
See port-m68k@ posts for more details:
