libc/eglibc: fix missing LIBC_TRY_CC_OPTION definition (eglibc 2.15)

Upstream SVN is currently broken:
http://www.eglibc.org/svn/branches/eglibc-2_15/libc/

LIBC_TRY_CC_OPTION macro is not defined in aclocal.m4.
This patch fix the configure script.

Once upstream branch will be fixed this patch could be reverted.

Related patch (committed to eglibc trunk):
Use autoconf macro for testing compiler options with empty input

     7 Attached is a patch to add __attribute__ ((noinline)) to

     8 call_gmon_start.

     9 

    10 Without this patch, the sec script that processed initfini.s removes a

    11 part of inlined call_gmon_start, causing undefined label errors.

    12 

    13 This patch solves the problem by forcing gcc not to inline

    14 call_gmon_start with __attribute__ ((noinline)).

    15 

    16 Tested by building for arm-none-lixux-gnueabi.  OK to apply?
