Two fixes: 1. `-Wl,a,b,c,d` is a comma separated list of linker arguments, we incorrectly assume key/value pairs, which runs into issues with for example `-Wl,--enable-new-dtags,-rpath,/x` 2. `-Xlinker,xxx` is not a think, so it shouldn't be parsed.

#
|
||
# 1. It allows Spack to swap compilers into and out of builds easily.
|

# 2. It adds several options to the compile line so that spack

# packages can find their dependencies at build time and run time:
|
||
# -I and/or -isystem arguments for dependency /include directories.

# -L arguments for dependency /lib directories.
