Remove -fexceptions configure test.

Browse source 
There is a configure test for -fexceptions.  This option was added in
GCC 2.8, so the test is obsolete - and indeed plenty of code is using
-fexceptions directly.  This patch removes the configure test and
makes all uses of $(exceptions) use -fexceptions directly.

Tested for x86_64 and x86 (testsuite, and that installed shared
libraries are unchanged by the patch).

	* sysdeps/arm/configure.ac (libc_cv_gcc_exceptions): Do not set
	variable.
