[LTP] [PATCH 2/2] syscalls/stime: detect if libc stime() is implemented dynamically

[Xiao Yang]

Don't alway skip libc stime() for Android, because bionic(Android libc)
may implement it in the future.

Note about formatting: maybe it'd be easier to edit the file if each function
was on separate line.

I hope AC_CHECK_FUNCS is working well on cross compilation (I guess so, but
noticed some problems on autotools with PKG_CHECK_MODULES, but that's different
as it's using pkg-config).

Agreed, also we have AC_CHECK_FUNCS() in the configure.ac so the best
step would be moving these there as well.

Other than that this is a great cleanup, thanks for doing this.

Hi Xiao, Cyril,

v2 has LTP_CHECK_LIBC_FUNCS in m4/ltp-libc-funcs.m4.
IMHO it'd be better to have simple AC_CHECK_FUNCS() in configure.ac, i.e. the
same way we handle AC_CHECK_HEADERS(). It might not be good to mix configure.ac
and m4/ltp-*.m4, but I guess general functions like this is easier to find in
configure.ac than in some of m4/ltp-*.m4.

Hi Petr,

Sorry, I missed your last comment.
It seems easier to remove LTP_CHECK_LIBC_FUNCS directly.

I will send v3 patch soon.

autotools fails preadv and pwritev detection with AC_CHECK_FUNCS for android
build [1]. Not sure if it's a problem of my setup or autotools bug.
