Similar to other architectures with IFUNC binutils/glibc support, this
patch enables the ifunc attribute for SPARC GNU/Linux. This is needed
for building glibc with the current checks on IFUNC resolver types
(and use of the attribute in glibc rather than manually created IFUNCs
is beneficial anyway because it results in better debug info).
Tested compilation of glibc (in conjunction with a glibc patch to
support using the attribute on SPARC) with build-many-glibcs.py. I
have not run the GCC tests for SPARC. OK to commit?
