/@unixroot is replaced by $UNIXROOT, which points a drive on which
programs following FHS are installed. This enables a program to find
a proper directory even if it is executed on a differrent drive from
the drive on which it is installed.
For examples, consider a program package installed on f: with
--prefix=/usr. That is, it is installed in f:/usr. Now, if it is
executed on a drive e: like this,
E:>f:/usr/bin/program
then PREFIX will be /usr. However /usr is on drive f: not drive e:.
So it will fail to find something based on PREFIX.
If using /@unixroot, it will be replaced by $UNIXROOT. In this case,
if UNIXROOT is set to 'f:', and PREFIX is /@unixroot/usr, then it will
translated to f:/usr.
* modules/configmake (UNIXROOT): New. /@unixroot on kLIBC, otherwise
empty string.
(PREFIX, EXEC_PREFIX, BINDIR, SBINDIR, LIBEXECDIR, DATAROOTDIR,
DATADIR, SYSCONFDIR, SHAREDSTATEDIR, LOCALSTATEDIR, RUNSTATEDIR,
INCLUDEDIR, OLDINCLUDEDIR, DOCDIR, INFODIR, HTMLDIR, DVIDIR, PDFDIR,
PSDIR, LIBDIR, LISPDIR, LOCALEDIR, MANDIR, MANEXT, PKGDATADIR,
PKGINCLUDEDIR, PKGLIBDIR, PKGLIBEXECDIR): Prepend UNIXROOT.
