Testcase - reduced input file from glibc

With this testcase the failing symbol is getcontext:

 16488: 0000000000000000   106 FUNC    WEAK   DEFAULT    2 __v1__getcontext
 16534: 0000000000000000   106 FUNC    GLOBAL DEFAULT    2 __getcontext
 16562: 0000000000000000   106 FUNC    WEAK   DEFAULT    2
getcontext@@GLIBC_2.2
 16570: 0000000000000000   106 FUNC    WEAK   DEFAULT    2
address@hidden
 16589: 0000000000000000   106 FUNC    WEAK   DEFAULT    2 __v2__getcontext
 16660: 0000000000000000   106 FUNC    WEAK   DEFAULT    2 getcontext

getcontext (as well as setjmp and others) on S/390 default to an older symbol
version in order to avoid the buggy versions in Glibc 2.19.
