[Minios-devel] [UNIKRAFT/NEWLIB PATCH 1/1] sincosl.c: Import from musl

[Vlad-Andrei BĂDOIU (78692) <vlad_andrei.badoiu@xxxxxxxxxxxxxxx>]

Copied as is from the official musl git mirror
git://git.musl-libc.org/musl, commit 6fcb440d.

We only keep the non optimized definition since
all the long double math functions from newlib
are wrappers over double.
