isr_tables: don't whole-archive library
As of today we have a bit weird situation with generated
sw_isr_table / irq_vector_table tables.
On the final linkage stage we pass two files which content
section with sw_isr_table / irq_vector_table. They are
* libarch__common.a (with an outdated tables from the first
linkage stage)
* isr_tables.c.obj (with an actual tables)
The sections where tables are located are marked with
".gnu.linkonce" prefix. That means:
<<<As a GNU extension, if the name begins with .gnu.linkonce,
we only link a single copy of the section.>>>
However the "libarch__common.a" is passed to linker with
"--whole-archive" option which means <<<include every object
file in the archive in the link, rather than searching the archive
for the required object files>>>
That combination confuses MWDT linker and breaks linkage with
MWDT toolchain.
As a simple fix we can move the sw_isr_table / irq_vector_table
sections to their own library and link this library with
"--no-whole-archive" option.
