When linked with 2.19.51.0.11 (which works), .rela.plt contains:
Relocation section '.rela.plt' at offset 0x1a0 contains 8 entries:
    Offset             Info             Type               Symbol's Value

  000000000047a030

where
  2532: 000000000047a030    68 IFUNC   WEAK   DEFAULT    6 stpncpy
  1394: 0000000000421a50    68 IFUNC   WEAK   DEFAULT    6 stpcpy

But when linked with trunk, this is:
00000000006c65d0  0000000000000025 R_X86_64_IRELATIVE

00000000006c6600  0000000000000025 R_X86_64_IRELATIVE

  000000000047a030

and the symbols are the same.  And indeed, the only changes between the two
binaries are 3 bytes in .rela.plt section:
 Relocation section '.rela.plt' at offset 0x1a0 contains 8 entries:
     Offset             Info             Type               Symbol's Value 
Symbol's Name + Addend

  0000000000421a50
and content of .note.gnu.build-id section.
