This commit https://sourceware.org/git/?p=glibc.git;a=commit;h=cd94326a1326c4e3f1ee7a8d0a161cc0bdcaf07e added the file `sysdeps/aarch64/fpu/bits/math-vector.h.

On a mantic system, the header file gets placed at /usr/include/aarch64-linux-gnu/bits/math-vector.h, which used to do only a single thing for aarch64, which was:
#include <bits/libm-simd-decl-stubs.h>

And after the commit, a few types are added such as

#if __GNUC_PREREQ(9, 0)
# define __ADVSIMD_VEC_MATH_SUPPORTED
typedef __Float32x4_t __f32x4_t;
typedef __Float64x2_t __f64x2_t;
...

Simply commenting out the new types is enough to fix this issue, but completely removing the newly added support for libmvec is not a great idea.

Perhaps nvidia-cuda-toolkit-gcc needs to be rebuilt with support for these types?
