[testsuite,android] Disabling thread_local4.C and thread_local4g.C for Android.

Hi,

for Android:

FAIL: g++.dg/tls/thread_local4.C -std=gnu++11 (test for excess errors)
Excess errors:
<>/gcc/testsuite/g++.dg/tls/thread_local4.C:31:26: error:
'pthread_testcancel' was not declared in this scope
<>/gcc/testsuite/g++.dg/tls/thread_local4.C:40:24: error:
'pthread_cancel' was not declared in this scope

the same for thread_local4g.C.

from http://www.kandroid.org/ndk/docs/system/libc/OVERVIEW.html
"pthread_cancel() will not be supported in Bionic, because doing this
would involve making the C library significantly bigger for very
little benefit.
<...>"

The following patch switches those tests off for Android.



is it ok for trunk?

Thank you,
Alexander

Alexander,

Your current patch as approved by Mike is OK, but it is more prudent to condition the tests on using Bionic libc, not the fact that target triplet has *-android* in it.  [E.g., it is possible to build a toolchain for, say, arm-linux-gnueabi which will use glibc for primary multilib, and bionic for secondary multilib.]

I didn't test the attached patch, so please confirm that it behaves as expected before applying it.

Thank you,

Maxim, thank you for your input! That's for sure a better solution.

__BIONIC__ is not defined in features.h so I had to change the include
to ctype.h. (__BIONIC__ is defined in sys/ctypes.h, but it's not safe
to include that directly..)

tested on x86_64_unknow_linux and on android device.

Is it OK?

thanks,
Alexander
