[Generics] undefined references for TTreeMaps in imports

[GWRon]

As reported via discord already, the following main file and its import file lead to an undefined reference error.

test.bmx

SuperStrict
Framework Brl.StandardIO

Import "importfile.bmx"

importfile.bmx

SuperStrict

Import Collections.TreeMap

Global trendsMap:TTreeMap<string, TTrendsEntry> = New TTreeMap<string, TTrendsEntry>()
Type TTrendsEntry
    Field key:Int
    Field value:String
End Type

Output:

[100%] Linking:test
/usr/bin/ld: /Testcodes/TreeMapTest/.bmx/importfile.bmx.release.linux.x64.o: in function `_bb_treemaptest_importfile':
importfile.bmx.release.linux.x64.c:(.text+0xfe): undefined reference to `gimpl_TTreeMapSTTTrendsEntry'

It works though, when placing the global inside the type:

Type TTrendsEntry
	Field key:Int
	Field value:String

	Global trendsMap:TTreeMap<string, TTrendsEntry> = New TTreeMap<string, TTrendsEntry>()
End Type

but fails when the global is defined within a Method (same if it is a Local). a Field works.

Type TTrendsEntry
	Field key:Int
	Field value:String

	Method Test()
		Global trendsMap:TTreeMap<string, TTrendsEntry> = New TTreeMap<string, TTrendsEntry>()
	End Method
End Type
