assembler files used when compiling with
assembler implementations.
shared_target => The shared library building method used.
- This is a target found in Makefile.shared.
+ This serves multiple purposes:
+ - as index for targets found in shared_info.pl.
+ - as linker script generation selector.
+ To serve both purposes, the index for shared_info.pl
+ should end with '-shared', and this suffix will be
+ removed for use as a linker script generation
+ selector. Note that the latter is only used if
+ 'shared_defflag' is defined.
build_scheme => The scheme used to build up a Makefile.
In its simplest form, the value is a string
with the name of the build scheme.
