We're starting to move IOCs from R3.14.11 to R3.14.12.3 and I've
noticed that C++ builds with host arch linux-x86_64 no longer have
debugging symbols by default, but C builds do. In R3.14.11 we used to
have debugging symbols on C and C++ builds even when NOT using the
linux-x86_64-debug architecture.

The change seems to be that in
R3.14.11/base/configure/os/CONFIG_SITE.Common.linux-x86_64 we have:

OP_SYS_CFLAGS += -g

But in R3.14.12.3/base/configure/os/CONFIG_SITE.Common.linux-x86_64
we have:

OPT_CFLAGS_YES += -g

My guess is that the change was probably made for a good reason, so
we should add the following line to
configure/os/CONFIG_SITE.Common.linux-x86_64:

OPT_CXXFLAGS_YES += -g

Is that the correct way to fix this?

Yes, Janet committed the fix below to the 3.14 branch just a few weeks ago:
