[edk2-devel] [Patch] BaseTools/Conf: Add new macro for customizing dll file reduction.

[edk2-devel] [Patch] BaseTools/Conf: Add new macro for customizing dll file reduction.

[Xu, Wei6]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3810

New macro OBJCOPY_STRIPFLAG is added in build_rule.template to replace
'--strip-unneeded -R .eh_frame', so that module can have some unique
objcopy flags for its own purpose.
In tools_def.template, set '--strip-unneeded -R .eh_frame' as default
value of OBJCOPY_STRIPFLAG.
