Patch: Make local functions static to avoid assembler error

SUMMARY

When building valgrind for Yocto-2.6 and using the musl libc rather than glibc,
a file in helgrind encounters an assembler error when building for qemumips/qemumips64.

STEPS TO REPRODUCE

On any desktop Linux system such as Ubuntu-18.04,
0. sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
 build-essential chrpath socat cpio python python3 python3-pip python3-pexpect \
 xz-utils debianutils iputils-ping libsdl1.2-dev xterm
1. git clone git://git.pokylinux.org/poky.git
2. cd poky.git
3. git checkout bc98a1e89dcd7b3f59f99e4382439d9028ba4db2
4. mkdir ../proj; cd ../proj
5. . ../poky.git/oe-init-build-env vg-bug
6. MACHINE=qemumips TCLIBC=musl bitbake valgrind

OBSERVED RESULT

the valgrind build fails an error:

several warnings:
 ../../../valgrind-3.14.0/helgrind/tests/annotate_hbefore.c:360:6: warning: no previous prototype for 'do_signal' [-Wmissing-prototypes]
    |  void do_signal ( UWord* w )
    |       ^~~~~~~~~
    

error:
    
    /tmp/cce22iiw.s: Assembler messages:
    /tmp/cce22iiw.s:446: Error: symbol `exit_0' is already defined
    /tmp/cce22iiw.s:448: Error: symbol `exit' is already defined
    /tmp/cce22iiw.s:915: Error: symbol `exit_0' is already defined
    /tmp/cce22iiw.s:917: Error: symbol `exit' is already defined


EXPECTED RESULT

valgrind builds without error.
