We should error out here.

Does musl supports /etc/ld.so.conf ? If so, then I believe we should
simply not use the /etc/ld.so.conf.d/ feature of glibc, and instead
keep using /etc/ld.so.conf only, like MySQL was doing.

If you don't want to see repeated entries, you can do something like:

	grep -q "^/usr/lib/mysql$" $(TARGET_DIR)/etc/ld.so.conf ||
		echo "/usr/lib/mysql" >> $(TARGET_DIR)/etc/ld.so.conf

We could even imagine having a make function to do that.

Best regards,

Thomas
