configure: Drop -Ttext checks for i386-pc

Browse Source 
The i386-pc target now uses a linker script, so -Ttext is no longer
required. However, a new variable TARGET_IMG_BASE_LDOPT_ARG_SEP is
introduced to handle the fact that when using --defsym the argument
separator must be "=". The space character is a syntax error.

Finally, EXTRA_DIST is updated to track the linker script used.
