final update for 0.9.27main

tccgen.c:
- fix ldouble asm hack
- fix a VLA problem on Win64 (also x86_64-gen.c)
- patch_type(): make sure that no symbol ever changes
  from global to static

tcc.c:
- tcc -vv: print libtcc1.a path also on win32

tccpe.c, tcctools.c:
- use unix LF mode to for .def output files (that is for
  creating reproducible output trees)

Makefile:
- suppress some warnings when makeinfo is missing
- call 'which install' only on win32

tests/Makefile:
- change PATH only on WINNT systems (i.e. not if cross-compiling
  on linux for win32)
- asm-c-connect.test: slim output and do diff

tccrun.c tccpe.c *-link.c:
- integrate former 'pe_relocate_rva()' into normal relocation
  This also fixes linkage of the unwind data on WIN64 for -run
  (reported by Janus Lynggaard Thorborg)

tccasm.c, tests/tcctest.c:
- fix dot (sym_index of -1 crashed in put_elf_reloc)
- massage .set a bit (see test)

other:
- #define SECTION_ABS removed
- ST_DATA Section *strtab_section: removed
- put_extern_sym2(): take int section number
