[PATCH v2] newlib: skip build of AArch64 80bit and 128bit long double functions when sizeof(double) == sizeof(long double)

[Radek Barton]

Hello.

Is there any further feedback on the second version of the patch? As far as I understand it, it does not make sense to build implementations in `aarch64/ld` folder at all if `_LDBL_EQ_DBL` is defined. Is that assumption correct?

Thank you.
