Laszlo Ersek 5c6ccd5324 BaseTools/tools_def.template: remove comment about GCC44 + LzmaF86Compress
"tools_def.template" currently suggests, in the documentation of the
LzmaF86Compress utility, that said tool is generally unhelpful on binaries
built with the GCC44 toolchain, relative to LzmaCompress.

This statement doesn't apply to the GCC48 toolchain. I compressed 126
NOOPT_GCC48/IA32 unique EFI modules (built with gcc-4.8.5, as part of
OVMF) with both LzmaCompress and LzmaF86Compress. I repeated the same for
117 NOOPT_GCC48/X64 unique EFI modules. On average, the LzmaF86Compress
output size was 92.4% of the LzmaCompress output size in the IA32 case
(best relative compression: 86.01%, poorest relative compression: 97.47%
-- still a win). In the X64 case, the LzmaF86Compress output size was
92.95% of the LzmaCompress output size, on avarege (best relative
compression: 87.69%, poorest relative compression: 97.65% -- again, still
a win).

Given the consistent improvement from LzmaCompress to LzmaF86Compress,
remove the statement (rather than updating it to GCC48).
