Well, 3604 is indeed more than size it checks (0x9000 - 0x8200 ==
3584). As I definitely can use beta1 on Linux for the same platform,
it looks like Cygwin related?

It has a .rdata section with following contents:
Contents of section .rdata:
9000 4743433a 2028474e 55292034 2e382e32 GCC: (GNU) 4.8.2
9010 00000000
We'll need to find an option to inhibit this

Even if I manually remove .ident "GCC: (GNU) 4.8.2" from generated
assembly file file, it still generates empty .idata section:
bor@server ~/grub-2.02~beta1
$ objdump -h grub-core/lzma_decompress.image.exe

Adding -Qn to TARGET_CFLAGS fixes it.
Small downside is, compiler used to generate files is no more present
in *.image and *.modules. May be we could stuff it in modinfo.sh to
facilitate debugging.
