bootstrap: add quoting support to avoid splitting

Browse Source 
With this change, it is now possible to pass quotes to the configure
script, such as

`./configure.py --set=target.\"thumbv8m.main-none-eabi\".linker=/linker`

, which will treat `thumbv8.main-none-eabi` as a whole part. Currently,
the string would be split into two elements: `thumbv8`, and
`main-none-eabi`.
