--- Comment #10 from Rich Felker <bugdal at aerifal dot cx> ---
musl uses ld64 for all powerpc targets because the ABI was designed when
compiler support for IEEE quad was not widespread, with an intent of suppor=
ting
existing compilers rather than requiring recent ones.

Since presumably libquadmath builds fine on other targets where ld is not i=
eee
quad or IBM double-double, I'm assuming it must be target-specific code tha=
t's
failing. Could libquadmath just fallback to using generic arch-agnostic cod=
e on
targets (including musl) where ld is not one of the currently supported one=
s?=
