Use AC_CHECK_DECL instead of a program.

Please properly wrap the calls. E.g., use the 2-space indents for inner blocks. Have a look at https://github.com/python/cpython/pull/142380/files#r2615800453 and the code I commented.

Added a check that not only do we have
stropts.h, butI_PUSHis also defined.I used
I_PUSHbecause it is used in two places (Modules/posixmodule.c,Modules/fcntlmodule.c), the rest of the definitions are only inModules/fcntlmodule.c.Also fix for gh-81541 if building without OpenPTY and without stropts.h.
