This helps in defining LE tunes and at the same time specifies
endianness on compiler cmdline clearly, clang e.g. defaults to
little-endian always, so unless specified with -mbig-endian won't
compile the code right

Default riscv is little-endian moreover most of other arches define
bigendian as tune and treats absense as litteendian, this make risc-v
fall in line

when compiling for ppc64, build emits additional
STANDARD_STARTFILE_PREFIX_1 and STANDARD_STARTFILE_PREFIX_2 into
gcc/defaults.h which is not conditional because it really want to
override others with this new value, but it ends up with two definitions
since it gets emitted _after_ the definition this patch moves to
default.h and ends up in duplicate defines.

Let the patch trigger based on target triplet instead of passing via
configure, this lets gcc compile for 64bit otherwise it ends up with
libgcc  build errors

error: unable to emulate 'TF'

-
-musl does not support ldbl 128 so we can not assume
-that linux as a whole supports ldbl-128 bits, instead
-act upon configure option passed to gcc and assume no
-on musl and yes otherwise if no option is passed since
-default behaviour is to assume ldbl128 it does not
-change the defaults
