### Description
I noticed that there was quite a bit missing from the mbed2 release of
the microbit today. That's because the microbit uses ARM by default and
the GCC_ARM small library. The release script was trying to release for
ARM using scan rules for uARM. Turns out we're stuck with 2 configuration
parameters for the same thing: `default_lib` for GCC and `default_toolchain`
for ARM. Dang

Currently the return value of flash_get_page_size() is 1 since the min size per one writing is 1 byte by Flash spec.
However, I noticed that this value causes a enormous write time When writing large data such as FW update.
So I revised this value to 8 byte by considering the writing time, memory alignment and memory hole.
Need to ensure the transmission has been started before sending a STOP condition.
Issue found on the NUCLEO_H743ZI due certainly to the high-speed clock used.
But this is normally needed also on all STM32 devices using the I2C peripheral version 2.

2 calls to `notify.cc_verbose` used the a FileRef object in place of
the file's name. Other calls to `notify.cc_info` would use just the
file name. This PR changes these 2 calls to be consistant with the rest.

### Description
The netbeans exporter was being inconsistant with it's invocation of
the C pre-processor on the linker script: the C pre-processor was always
invoked from `$PATH` where as the rest of the tools were invoked as
configured by the tools. This changes the invocation of CPP to match the
rest of the tools: heed the conifguration.
