2017-11-13PE: don't corrupt section flags when linking from ELF objectsJan Beulich
Linking EFI executables from ELF object files can result in corrupted COFF section flags if the section's alignment is too high. Issue a diagnostic in that case, erroring out if this is not a final link, and make sure only in-range values get written to the output image. While doing this also make tic80 use the generic alignment macros instead of custom #ifdef-ary. No testsuite regressions for the range of COFF/PE targets that actually cross-build in the first place on x86-64-linux.
