You have some flavours, e.g.

+#define GLIBC_DYNAMIC_LINKER32 RUNTIME_ROOT_PREFIX "/lib/ld-linux.so.2"
+#define GLIBC_DYNAMIC_LINKER64 RUNTIME_ROOT_PREFIX
"/lib64/ld-linux-x86-64.so.2"

or

+#define UCLIBC_DYNAMIC_LINKER RUNTIME_ROOT_PREFIX "/lib/ld-uClibc.so.0"
+#define UCLIBC_DYNAMIC_LINKER32 RUNTIME_ROOT_PREFIX "/lib/ld-uClibc.so.0"
+#define UCLIBC_DYNAMIC_LINKER64 RUNTIME_ROOT_PREFIX "/lib/ld64-uClibc.so.0"

And you add some prefix to it.

while the correct patch would just wipe all this cruft and have a

DYNAMIC_LINKER_{32/64/default} and a mean to set it.

Everything is still not exactly great since you could have more than 2
abis per architecture.

As said the patch is surely an improvement over the previous situation
but doesn't help solving the problem fully.
