-commit 00571b43df2e "libc: posix_fadvise: restore implementation for xtensa"
-enabled posix_fadvise() for all arches (it was just not generated
-before).
-
-However this also unearthed an issue introduced by ee84b8b400
-"linux: posix_fadvise: use new SYSCALL_ALIGN_64BIT" which is to
-referencing LFS'ish code (off64_t) w/o proper checks which causes build
-to break for !LFS.
-
-Fix this by calling posix_fadvise64() only for LFS case and open-code
-it's equivalent for !LFS.
