some improvements on ncurses

[ghost]

hi

i wanted to cross compile my project that uses this library for arm64 linux from an x86_64 linux host,

i used xmake f -p cross --cross=aarch64-linux-gnu- (i have the cross gcc and binutils installed on my host, sysroot is at /usr/aarch64-linux-gnu and gcc is prefixed by aarch64-linux-gnu- and its installed to /usr/bin),

but i had got a problem while configuring, a warning complains about ncurses is not supported for cross/arm64,
so i had a quick check of the source and found the supported platform list is hardcoded...

but luckily after removing it and tweaking some ac config options, it does seems to build and work with my original project.

also i thought adding these extsources might make it more friendly for some users?

another weird behavior is i cannot use linux as platform type

these attempts were failed (because it detects x86_64 which is my host architecture, and it's wrong since i am trying to cross compile for arm64):

❯ xmake f -m debug -p linux --cross=aarch64-linux-gnu-
checking for architecture ... x86_64
^C
❯ xmake f -m debug -p linux --cross=aarch64-linux-gnu- --bin=/usr/bin --sdk=/usr/aarch64-linux-gnu
checking for architecture ... x86_64
^C

it detects x86_64 which is my host architecture

i tried to correct it by specifying -a arm64 manually, but the build still eventually fail at some where...

i have also tried vcpkg, but it ran into this issue:

❯ vcpkg install ncurses:arm64-linux

humm, looks like windows and macos builds are broken?

you need remove --without-progs and we should disable windows platform.

i do have a windows and mac pc, so i guess let's see when i will have chance to test build on them and fix...
