When compiling the binutils on some systems, the ld link fails. The reason is
that the generated emulation C file is empty.
By looking at the make output, we can see
.../genscripts.sh: line 403: ${BASH_LINENO[0]} + 1: bad substitution
However, no error is detected, and the build process of ld continues until the
final link, which fails.
This happens when $(SHELL) is actually bash compiled with the --enable-minimal-
config option. In that case, the variable BASH is set, but the array
BASH_LINENO is not supported.
The problem is at the bottom of ld/genscripts.sh
If it is supported by the shell, line number information is inserted into the
generated emulation source, by using BASH_LINENO. However the detection method
is wrong. It assumes that if the BASH variable is set, the BASH_LINENO array
will be available, which is not always true.
