[PATCH/BUG] ld/Makefile.am: missing dependency on ldscripts/stamp for e%.c target

[A B C]

Sorry but no

# These all start with e so 'make clean' can find them.
ALL_EMULATION_SOURCES = \
eaix5ppc.c \
eaix5rs6.c \
eaixppc.c \
eaixrs6.c \
ealpha.c \
eelf32simplecpu.c \

and in order to make it works for me I just added mkdir -p ldscripts in
genscripts.h

# Create scripts using different settings of the LD_FLAG variable
mkdir -p ldscripts
LD_FLAG=r
