[PATCH 1/4] ld: In map file use '=' in PROVIDE statements

[Andrew Burgess <andrew.burgess@embecosm.com>]

Currently when recording a PROVIDE statement in a linker script we
display something like:

    PROVIDE (SYMBOL, VALUE)

However, in linker scripts we write these statements like this:

    PROVIDE (SYMBOL = VALUE);

This commit changes the format in the map file to be closer to linker
script format, the map file now contains:

    PROVIDE (SYMBOL = VALUE)

ld/ChangeLog:

	* ldexp.c (exp_print_tree): Use '=' instead of ',' when printing
	PROVIDE statements.
	* testsuite/ld-scripts/provide-4.map: Update expected output.
	* testsuite/ld-scripts/provide-5.map: Likewise.
