Fix capital case of setjmp_test and gctest in README and comments

* Makefile.direct (HOSTCFLAGS): Start setjmp_test word with lower case
in comment.
* README.md (Installation and Portability): Likewise.
* mach_dep.c (GC_with_callee_saves_pushed): Likewise.
* tools/setjmp_t.c (main): Likewise.
* Makefile.direct (setjmp_test): Start gctest word with lower case in
comment.
* OS2_MAKEFILE (CFLAGS): Likewise.
* README.md (Installation and Portability): Likewise.
* SMakefile.amiga (finalize.o): Likewise.

 Below we focus on the collector build using classic makefile.
 For the Makefile.direct-based process, typing `make check` instead of `make`
 will automatically build the collector and then run `setjmp_test` and `gctest`.
