configure.ac: MJIT_DLDFLAGS_NOCOMPRESS

is configured now, to force -Wl,--compress-debug-sections=no
for MJIT only when the option is used in MJIT_DLDFLAGS.

This needs to be done in configure.ac to resolve build failure like
https://travis-ci.org/ruby/ruby/builds/415120662.

Makefile.in: define it in mjit_config.h

mjit_worker.c: replace hard-coded flag to MJIT_DLDFLAGS_NOCOMPRESS
