fix symbols padding in linker script + slim header
the new system uses a preprocessed linker script in order to place an alias within each captured section.
the following code is generated for each symbol:
.text.x86_codd : { "x86_dasm" = "."; *(.text.x86_codd); }
additionally, a new "slim header" has been added.
it's a preprocessed variant of the current "xzre.h" which doesn't depend on external headers
and can be loaded by other tools- Loading branch information
