RFR/RFC: Non-PCH x86_32 build failure: err_msg is not defined

[Aleksey Shipilev]

Bug:
 https://bugs.openjdk.java.net/browse/JDK-8200438

Obvious fix:

The non-obvious part (and thus, "RFC") is why x86_64 build works fine in the same config. I don't
have the answer for that.

Testing: x86_32 build
