The reasons for this failure are outlined in PR #19846

On Linux there is no C 'long double' type unless arch==(x86_64) || arch(i386)

Therefore the "powl" test should be disabled for Linux "other archtypes" until support is added.

Or maybe it should default to "Double"?

/// The C 'long double' type.
#if os(OSX) || os(iOS) || os(watchOS) || os(tvOS)
// On Darwin, long double is Float80 on x86, and Double otherwise.
#if arch(x86_64) || arch(i386)
public typealias CLongDouble = Float80
#else
public typealias CLongDouble = Double
#endif
#elseif os(Windows)
// On Windows, long double is always Double.
public typealias CLongDouble = Double
#elseif os(Linux)
// On Linux/x86, long double is Float80.
// TODO: Fill in definitions for additional architectures as needed. IIRC
// armv7 should map to Double, but arm64 and ppc64le should map to Float128,
// which we don't yet have in Swift.
#if arch(x86_64) || arch(i386)
public typealias CLongDouble = Float80
#endif
// TODO: Fill in definitions for other OSes.
#endif
