In some cases you do not want to use the built-in optimizing linker. You
can only use GCC by (for example):

    EnvironmentLinker:	/usr/bin/gcc::-g -lmysqlclient|... (other
    linkers)

Note that :: ensures the options are passed to gcc.

Support options2 for linker as well

See merge request !5

cpm: Support adding multiple paths

See merge request !4

The following entry in IDEEnvs:
EnvironmentLinker:	lib/exe/linker:-h 200m:-lmysql

Will call the linker with a heap of 200M and pass -lmysql to gcc/ld

In some extravagant cases (large projects with descriptors etc.), the
linker needs more heap as well
