[Mono-list] libgc6 on libc2.2.5 requires -ldl

[Ulrich Kunitz]

Hi,

I compiled today mono from the cvs. However calling

configure --with-gc=boehm

doesn't work out of the box with libgc6 and libc 2.2.5. Linking of
libdl for dlopen() is also required.

This patch of configure.in worked for me, but might break on other
configurations:
