libstdc++: Fix simd build failure on clang

Clang does not support __attribute__ on lambdas. Therefore, only set
_GLIBCXX_SIMD_ALWAYS_INLINE_LAMBDA if __clang__ is not defined.

Signed-off-by: Matthias Kretz <m.kretz@gsi.de>
libstdc++-v3/ChangeLog:

	PR libstdc++/108030
	* include/experimental/bits/simd_detail.h
	(_GLIBCXX_SIMD_ALWAYS_INLINE_LAMBDA): Define as empty for
	__clang__.
