[GMP build] rm: invalid argument: `' with coreutils 8.0

[Vincent Lefevre]

Hi,

When building GMP 4.3.2 and GMP 5.0.0 under Linux (Debian/unstable,
x86_64), I get error messages:

  rm: invalid argument: `'

e.g.

[...]
Making all in mpn
make[2]: Entering directory `/home/vlefevre/software/gmp-5.0.0/mpn'
/bin/bash ../libtool --mode=compile gcc -std=gnu99 -DHAVE_CONFIG_H -I. -I. -I.. -D__GMP_WITHIN_GMP -I.. -DOPERATION_`echo fib_table | sed 's/_$//'`    -O2 -pedantic -m64 -mtune=core2 -march=core2 -c -o fib_table.lo fib_table.c

rm: invalid argument: `'
[...]

This doesn't seem to have any side effects, though.

Note that with the coreutils 8.0,

  rm -f ''

is an error.
