[PULL 06/21] tests/tcg: Fix some targets default cross compiler path

[Alex Bennée]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

We do not want a shell command substitution, but a parameter
substitution (with assignment). Replace $() -> ${}, otherwise
the expanded command return an empty string and the $cross_cc
variable is not set.

Fixes: 634ef789f8e ("tests/tcg: add more default compilers to configure.sh")
