[PATCH] options: fix cl_target_option_print_diff() with strings

[Eric Biggers via Gcc-bugs]

Fix an obvious copy-and-paste error where ptr1 was used instead of ptr2.
This bug caused the dump file produced by -fdump-ipa-inline-details to
not correctly show the difference in target options when a function
could not be inlined due to a target option mismatch.

gcc/ChangeLog:

        * optc-save-gen.awk: Fix copy-and-paste error.

Fixes: b54ecc769f59 ("re PR bootstrap/90543 (Build failure on MINGW for 
gcc-9.1.0)")
