Right, I understand the situation, but it's done that way on purpose.
That's the reason that the extensions/sial.mk file has this:

all:
        @if [ -f /usr/bin/flex ] && [ -f /usr/bin/bison ]; then \
          if [ -f ../$(GDB)/crash.target ]; then \
            make -f sial.mk sial.so; else \
          echo "sial.so: build failed: requires the crash $(GDB) module"; fi \
        else \
          echo "sial.so: build failed: requires /usr/bin/flex and /usr/bin/bison"; fi

i.e., precisely for situations like yours, but where a user does not have flex
and bison installed, and has no interest in SIAL.  The idea is to keep the upstream
spec file as unrestrictive as possible.

Is it possible to restrict the BuildRequires to only the extensions subpackage?
