The !uClibc dependency is also not sufficient: indeed, musl too does not provide _fpu_control; only glibc does. This is the same situation as for clapack. Add a comment about this, to mirror clapack. Since the !glibc dependency only exists for PowerPC, treat it as an architecture dependency. Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <redacted> [yann.morin.1998@free.fr: - fpu_control depends on glibc, not on !uclibc - add or update comments accordingly ] Signed-off-by: Yann E.
