The passage from /usr/include/sys/mman.h looks like:

#if (_POSIX_C_SOURCE > 2) || defined(_XPG4_2)
[...]
#else   /* (_POSIX_C_SOURCE > 2) || defined(_XPG4_2) */
[...]
#if !defined(_XOPEN_SOURCE) && !defined(_POSIX_C_SOURCE) || \
        defined(__EXTENSIONS__)
extern int getpagesizes(size_t *, int); /* <<== That, we want */
[...]
#endif /* !defined(_XOPEN_SOURCE) && !defined(_POSIX_C_SOURCE)... */
[...]


In the recipe, you specify

 EXTRA_CFLAGS = -mt -D_POSIX_C_SOURCE=199506L -D__EXTENSIONS__

Hence _POSIX_C_SOURCE > 2, and getpagesizes() will not be declared.

Is there any particular reason for defining _POSIX_C_SOURCE? I just built it
successfully without _POSIX_C_SOURCE for sparcv8plus on unstable9s.
