Still it works witch cmake. (The message claims: "Should not be used on Linux", but of
course it might)

The problems starts with the compilation of localcharset.c, plenty of warnings
(-Wunused-parameter)

The first error is
/usr2/src/lyx/lyx-test/3rdparty/libiconv/1.15/libcharset/lib/localcharset.c:77:38: error:
expected expression before ‘)’ token # define relocate(pathname) (pathname)

Apparently ENABLE_RELOCATABLE is not defined.
Checking the preprocessed in cmake, "ENABLE_RELOCATABLE 1" is done at command line
...
#define __ELF__ 1
#define __DECIMAL_BID_FORMAT__ 1
# 1 "<command-line>"
#define BUILDING_LIBCHARSET 1
#define ENABLE_RELOCATABLE 1
#define HAVE_CONFIG_H 1
...
