>Description:
arch/aarch64/softfloat/qp.c contains a definition of __trunctfdf2.

However, this function is also defined in libgcc, which creates
problems when static linking:

ld: /usr/lib/libc.a(qp.o): in function `__trunctfdf2':
qp.c:(.text+0x110): multiple definition of `__trunctfdf2';
/usr/lib/libgcc.a(trunctfdf2.o):trunctfdf2.c:(.text+0x0): first defined here
