This change fixes the C99 math function support in <cmath> on
hppa64-*-hpux11*.
Tested on hppa64-hp-hpux11.11 and x86_64-linux-gnu. See:
https://gcc.gnu.org/pipermail/gcc-testresults/2024-February/809158.html

Okay for trunk?

Fix cmath math declarations and stub support for hppa64-*-hpux11*
This change fixes the following issues:
1) When the target host system doesn't support the full set of C99
functions, the stub replacements are not declared by cmath. As a
result, stub replacements do not become members of namespace std.
2) Some using statements for float and long double C99 functions
are surrounded by a _GLIBCXX_HAVE_* #ifdef. For example,
#ifdef _GLIBCXX_HAVE_ACOSF
using ::acosf;
#endif
As a result, missing float and long double functions never become
a member of std even though there is stub support for all of them.
3) Undefs for acosf, acosl, etc, are missing. Adding these should
allow PR86553 to be fixed.
4) Added AC_DEFINE statements for HAVE_CBRTF, HAVE_COPYSIGNF,
HAVE_HYPOTF, HAVE_LOG2F and HAVE_NEXTAFTERF to crossconfig.m4
for hpux host.
5) Added additional checks to linkage.m4.
6) Added stubs for missing float, double and long double C99
functions.
