Subject: [PATCH] Updates headers for glibc-2.42

Match the extern definitions in cuda-crt headers with the changes in glibc-2.42.

/usr/include/bits/mathcalls.h(206): error: exception specification is
incompatible with that of previous function "rsqrtf" (declared at line 657 of
/opt/cuda/bin/../targets/x86_64-linux/include/crt/math_functions.h)

extern float rsqrtf (float __x) noexcept (true); extern float __rsqrtf (float
__x) noexcept (true);
