[package] libiconv/1.17: fails to build with clang on Windows

[mmomtchev]

Description

libiconv fails to build with clangon Windows - this is a different problem from the other iconv problems:

#20848
#20477

This is a more recent problem that seems to be common throughout the autotools-based recipes when using clang.

Package and Environment Details

• Package Name/Version: libiconv/1.17
• Operating System+version: Windows
• Compiler+version: LLVM/clang 18.1.8
• Conan version: conan 2.7.0
• Python version: Python 3.10.9

[mmomtchev]

That class of problems is caused by a GNU make that cannot read cygwin-style paths (/c/users...), using the GNU make from MSYS2 fixes the problem - maybe these recipes should pull the dependency

[mmomtchev]

The problem is that make/4.4.1 from conan has the same problem while the make.exe from msys2/cci.latest does support this style of paths, however it does not work with CMake.
