flasm: fix build on gcc-10 (-fno-common)
Brought to you by:
ikogan
gcc-10 changed the default from -fcommon to fno-common:
https://gcc.gnu.org/PR85678
As a result build fails as:
ld: unflasm.o:/build/source/unflasm.c:32: multiple definition of
`swfVersion'; flasm.o:/build/source/flasm.c:36: first defined here
The change makes 'swfVersion' a local variable to flasm and unflasm binaries.
