Yes, see below.

You can put both -Bdynamic and -Bstatic in a command line. According to ld's 
manual, these options affects library searching with -l options which follows 
it. Which means if you do -Bdynamic -lfoo -lbar -Bstatic -lbaz libfoo and 
libbar will be dynamically linked and libbaz will be statically linked.

-L takes as a parameter a directory containing libraries. You should either 
specify libgcc.a as an input file (as you would for a .o, .s or .c file) or use 
-Bstatic (or variants of this option) to load libgcc as static.
