Details:
There are thousands of makefiles containing logic like this
uname := $(shell uname -s) # or worse, "="
ifneq (,$(filter Linux,$(uname)))
LINUX_HOST := 1
else ifneq (,$(filter CYGWIN%,$(uname)))
CYGWIN_HOST := 1
else ...
endif
This is complicated, duplicative, hard to read, has portability issues due to
relying on a Unix utility, etc. Meanwhile make already contains a variable
"make_host" describing the platform it was built for, and a one-line patch can
make it available within makefiles:
define_variable_cname ("MAKE_HOST_TYPE", make_host, o_default, 0);
The attached patch also includes documentation.
