MIPS, SPARC: fix wrong vfork aliases in libpthread.so
With recent binutils versions the GNU libc fails to build on at least MISP and SPARC, with this kind of error: /home/aurel32/glibc/glibc-build/nptl/libpthread.so:(*IND*+0x0): multiple definition of `vfork@GLIBC_2.0' /home/aurel32/glibc/glibc-build/nptl/libpthread.so::(.text+0xee50): first defined here It appears that on these architectures pt-vfork.S includes vfork.S (through the alpha version of pt-vfork.S) and that the __vfork aliases are not conditionalized on IS_IN (libc) like on other architectures. Therefore the aliases are also wrongly included in libpthread.so. Fix this by properly conditionalizing the aliases like on other architectures. Changelog: * sysdeps/unix/sysv/linux/mips/vfork.S (__vfork): Conditionalize hidden_def, weak_alias and strong_alias on [IS_IN (libc)]. * sysdeps/unix/sysv/linux/sparc/sparc32/vfork.S: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/vfork.S: Likewise. (cherry picked from commit 43c2948756bb6e144c7b871e827bba37d61ad3a3) (cherry picked from commit 80bf719031867f6afa96be7813f4dea1296d6bfd)
