We were never going to be capable of supporting every single part
variant with their own files, so stop trying. We've been supporting the
linker script generator for a long time now, so move on from these old
static files.
Breaking: if you were using one of these, and don't wish to use the
linker script generator, you should simply declare a stub linker script,
and include the generic section definitions file, and provide this in
your own application.
Old:
LDSCRIPT = $(OPENCM3_DIR)/lib/stm32/l1/stm32l15xxb.ld
New (linker script generator):
DEVICE=stm32l151cb
New (manual):
* Add file mymemorymap.ld, with contents similar too:
```
MEMORY
{
rom (rx) : ORIGIN = 0x08000000, LENGTH = 256K
ram (rwx) : ORIGIN = 0x20000000, LENGTH = 48K
}
/* Include the common ld script. */
INCLUDE cortex-m-generic.ld
```
LDSCRIPT=mymemorymap.ld
See ld/README for more information on using the linker script generator
The leading - makes it rather inconsistent with the majority of other
projects around the world. Use the form everyone else uses.
To solve this, properly pass prefix to inner makes as was always
intended.

The original submitter of this squished everything into one series, and
has not returned. The code mostly appears good, and review comments were
followed for the most part. The project doesn't really maintain any
testing or board farm for sam3/sam4 parts, so we're going to just trust
our users.
