Hi all,

After merging the rust tree, today's linux-next build (x86_64
allmodconfig) failed like this:

scripts/kconfig/confdata.c: In function 'rustc_cfg_print_symbol':
scripts/kconfig/confdata.c:669:9: warning: implicit declaration of function 'sym_escape_string_value'; did you mean 'sym_set_string_value'? [-Wimplicit-function-declaration]
669 | str = sym_escape_string_value(value);
| ^~~~~~~~~~~~~~~~~~~~~~~
| sym_set_string_value
scripts/kconfig/confdata.c:669:7: warning: assignment to 'const char *' from 'int' makes pointer from integer without a cast [-Wint-conversion]
669 | str = sym_escape_string_value(value);
| ^
/usr/bin/ld: scripts/kconfig/confdata.o: in function `rustc_cfg_print_symbol':
confdata.c:(.text+0x738): undefined reference to `sym_escape_string_value'

Caused by commit

dc08d49444e9 ("Kbuild: add Rust support")

interacting with commit

420a2bdbead2 ("kconfig: Refactor sym_escape_string_value")

from the kbuild tree.

I applied the following patch, but it doesn't seem quite right.
