DMD fails to invoke LINK.EXE for the build of `d_do_test.d`.

config file (C:\Users\khara\sc.ini) :
---
[Version]
version=7.51 Build 020

[Environment]
LIB="%HOME%\dmd2\windows\lib";%HOME%\dm\lib
DFLAGS="-I%HOME%\dmd2\src\phobos" "-I%HOME%\dmd2\src\druntime\import"
LINKCMD=%HOME%\dmd2\windows\bin\link.exe
---

environment variables:
---
> echo %HOME%
C:\Users\khara

command lines and outputs:
---
> cd C:\Users\khara\dmd2\src\dmd\test          # move to test directory C:\MinGW\msys\1.0\bin\make       # run makefile with GNU make in MSYS

================

That is a specific problem for the MSYS environment. With cygwin environment, the problem does not occur.

When dmd invoked from MSYS make, getenv("HOME") returns "C:/Users/khara"
instead of "C:\Users\khara" (note that the path separator difference).

MinGW bug tracker report: http://sourceforge.net/tracker/?func=detail&atid=102435&aid=1100932&group_id=2435

When reading sc.ini, DMD will try to expanding %HOME% environment variable for LINKCMD, but it is expanded to "C:/Users/khara\dmd2\windows\bin\link.exe" under the MSYS, then dmd fails to invoke link command which has the mixtured path separators.

From the MSYS source code, LD_LIBRARY_PATH, TMPDIR, TMP, and TEMP have same
issue.
http://mingw.git.sourceforge.net/git/gitweb.cgi?p=mingw/msys-runtime;a=blob;f=winsup/cygwin/environ.cc;h=b88ca3d39d8d77a4d38be3fcd09e2fa8bbd0c265;hb=77f2469b25911ceebae6741cbd2fa1b0ff6b1d6e#l61

So, this is not actually the bug of DMD, but I think we should add a workaround to support development with MSYS.

To resolve the problem, DMD should normalize path separator on the link command invocation.
