The same way as any other sections.  Dynamic sections are normal
sections.  It is just that they contain information that is used by
dynamic linkers/loaders to resolve symbols and relocations are load
time instead of link time.

Sounds excellent.

Indeed there is.  In the ld sources there is a directory called
'testsuite' which contains tests which can be run using a dejagnu /
expect framework.  Tis testsuite can be run by the build target "make
check" in much the same way that gcc can be tested.
