uclibc: disable DOPIC on ARM FLAT

Browse Source 
As explained by Waldemar, enabling DOPIC in uClibc will lead to the
creation of a Position Independent library. In turn, this will cause
elf2flt to generate a "Has-PIC-GOT" flat binary, which doesn't work on
ARM. In fact, elf2flt on ARM really expect to have non-PIC code as
input, so we must disable DOPIC in the uClibc configuration.
