[PATCH 11/11] alpha: run the ld-ifunc tests

Removing alpha from the skip list in ld-ifunc/ifunc.exp runs the tests
there. Tested with an alpha-linux-gnu cross toolchain; only the link
tests of that directory are supported in a cross configuration.

ifunc-26 stays an expected failure, as it has been since commit
bb4e012ca04 added the marker. It is not a linker limitation: the test
assigns a symbol with .set, which tc-alpha reads as the directive that
sets an assembly mode.

+* The alpha target supports indirect functions (STT_GNU_IFUNC), using the
+  newly allocated R_ALPHA_IRELATIVE (42) dynamic relocation.  No dynamic
+  linker or C library startup code implements that relocation yet, so a
+  program that uses an indirect function needs a matching C library to run.
+  Taking the address of one from a read-only section is not supported in a
+  static link.
+
 * The avr target supports .gnu_attribute 4 (Tag_GNU_AVR_VTABLE_AS).
