Multiple definitions of setregid, setresgid and setresuid between libc/libpthread

[Thomas Petazzoni]

Hello,

Similar problem than with vfork() (redefinition of symbols between
libpthread.a and libc.a), but this time with setregid(), setresgid()
and setresuid(), triggered by the build of Python on at least two
architectures:

 * i386

 * ARM

Same uClibc version as with the vfork() report: 0.9.33.2 plus the set
of patches at
http://git.buildroot.net/buildroot/tree/package/uclibc/0.9.33.2?id=2014.05-rc1.

Best regards,

Thomas
