arm: setjmp/longjmp: fix PIC vs SHARED thinkos
The logic in setjmp/__longjmp incorrectly uses "PIC" to figure out whether the code is going into a shared library when it should be using "SHARED". If you build glibc with a gcc version that has PIE enabled by default, then the code will try to use symbols that are only in the shared library. URL: https://bugs.gentoo.org/336914
