The orign_path.patch introduced '_dl_strchr' in ldso/ldso/dl-elf.c, and
caused the following undefined referencing compiling error:
| .../libdl.a(libdl.os): In function `search_for_named_library':
| .../dl-elf.c:156: undefined reference to `_dl_strchr'
| collect2: error: ld returned 1 exit status
I found this problem when compiling gdb in static mode using uclibc.
So, add the definition of '_dl_strchr' to fix it. The '_dl_strstr' is
added as well.
And I regenerated a patch to replace the original one.

+However, the above patch introduced '_dl_strchr' in ldso/ldso/dl-elf.c,
+and caused the following undefined referencing compiling error:

+ | .../libdl.a(libdl.os): In function `search_for_named_library':

+This problem would be reproduced through compiling gdb in static mode

+So, add the definition of '_dl_strchr' to fix it. The '_dl_strstr' is
