x86 32bit build broken

[Manuel Lauss]

Hi Noah,

Since commit c22eb807b0 ("x86: Rename generic functions with unique
postfix for clarity"),
building 32bit x86 glibc is broken:

../sysdeps/i386/i686/multiarch/strcspn-c.c:3:11: fatal error:
sysdeps/x86_64/multiarch/strcspn-c.c: No such file or directory
   3 | # include <sysdeps/x86_64/multiarch/strcspn-c.c>
     |           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
../sysdeps/i386/i686/multiarch/strpbrk-c.c:2:10: fatal error:

     |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
