Defining an alias of an IFUNC symbol must also create an IFUNC symbol. It makes
no sense to define a normal FUNC symbol since calling it returns nonsense.
.text
.type foo, @gnu_indirect_function
.globl foo
foo: .long 1
.size foo, .-foo
.globl __foo
.set __foo, foo
Assembling this code leads to this symbol table in the file:
4: 0000000000000000 4 GNU_IFUNC GLOBAL DEFAULT 1 foo
5: 0000000000000000 4 FUNC GLOBAL DEFAULT 1 __foo
This is with rawhide's 2.19.51.0.2-18.fc11.
