I did a find for this variable, but looks like it was not defined. 
$ find . -exec grep V8DBG_OFF_FP_CONTEXT {} \; -print
grep: can't open ./tools/eslint/node_modules/.bin/eslint
#define V8_OFF_FP_CONTEXT           V8DBG_OFF_FP_CONTEXT

Sounds a lot like #1967 and #7840. I don't think we ever truly resolved those issues but the reporter from the second issue reported that upgrading to v6.x fixed the issue for them; upgrading your toolchain, binutils in particular, may help too. If all else fails, build with ./configure --without-dtrace && make.

FWIW, the symbol is generated by deps/v8/tools/gen-postmortem-metadata.py; grep for 'off_fp_context'. It maps to StandardFrameConstants::kContextOffset, which is certainly in use.

Updating binutils from 2.23.1 to 2.26 resolved the issue. I think the issue can be closed.
