8c1e35c Ninja: remove some unused default arguments
7f647cf Ninja: also write link libraries to rsp file
Since commit 7ced0732 (make default install component name configurable,
2012-05-13) the COMPONENT option has not worked in all cases. The
change restored use of the broken SetDefaultString previously removed by
commit 43cad3e4 (fix the default "Unspecified" component, 2008-03-26).
Remove SetDefaultString and use the default component name only when an
invocation does not specify a non-empty COMPONENT option value.

A common mistake is to write
macro(foo arg)
if(arg)
endif()
endmacro()
and expect if() to treat "arg" as a variable. The documentation of the
macro() command already states that arguments are not variables, but
users writing the if() command may not look at the macro() docs.
Add a note to the if() documentation.
The work around is only needed by older GCCs (only testet 4.4/4.7)
Ninja is very new so chances are high that there is also a new mingw.
Use slashes in link rsp file, because ar.exe can't handle \.
Among other flags this sets RPATH flags correctly so that CMake knows
how to treat CMAKE_PLATFORM_REQUIRED_RUNTIME_PATH for the ASM language.
This is the GNU compiler equivalent to commit a0bab7ae (Add ASM platform
information for XL compiler on AIX, 2011-03-02), made for XL.
Previously CMake silently accepted the empty string and added a bogus
dependency on the current directory. Instead warn about the empty file
name and ignore it. We cannot make this an error because there may be
existing projects that accidentally depend on the old behavior.
Add a RunCMake.include test to cover this case.
Otherwise when linking 'CustomCommand' some linkers report
ld: 0711-224 WARNING: Duplicate symbol: .main
